095 - Center of Mass
In this video Paul Andersen explains how the center of mass of an object represents the average position of matter in an object. The center of mass of a system is a combination of all the objects within the system. As long as no external torque is applied to the system the center of mass will be conserved.

Center of Mass and stability demonstrations
It is useful to note that the mass-center is a fixed property for a given rigid body (e.g. with no slosh or articulation), whereas the center-of-gravity may, in addition, depend upon its orientation in a non-uniform gravitational field. In the latter case, the center-of-gravity will always be located somewhat closer to the main attractive body as compared to the mass-center, and thus will change its position in the body of interest as its orientation is changed.
In the study of the dynamics of aircraft, vehicles and vessels, forces and moments need to be resolved relative to the mass center. That is true independent of whether gravity itself is a consideration. Referring to the mass-center as the center-of-gravity is something of a colloquialism, but it is in common usage and when gravity gradient effects are negligible, center-of-gravity and mass-center are the same and are used interchangeably.

This calculus video tutorial provides a basic introduction into the center of mass of a system also known as the centroid. It explains how to find the x and y coordinates of the centroid of a planar lamina which is a 2d region. The center of mass occurs where an object or a region can be balanced by a pencil if gravity is the only force acting on it. This video contains plenty of examples and practice problems.
Here is a list of topics:
1. Center of mass for a one-dimensional system
2. Seesaw example
3. Finding the center of mass for a two-dimensional system
4. Center of mass of a planar lamina
5. Moment about the origin
6. Moment about the x-axis
7. Moment about the y-axis
8. Surface Density vs Linear Density

Script:
The centre of mass of an object is the point where the entire weight of an object appears to act. Working out the centre of mass of a symmetrical object is easy; it’s simply the point where the lines of symmetry cross.
However it’s very unlikely that you’ll be dealing with such perfect shapes so you work it out by suspending the object freely, along with a plumb line. The centre of mass is always below the point of suspension, so by marking the vertical along the plumb line you know the centre of mass is somewhere along that line. By suspending the object from another point and repeating the process, you get two lines that intersect and the point of intersection is the centre of mass.
The position of the centre of mass is very important when it comes to the stability of an object. For example, a double decker bus is built to have a very low centre of mass and a wide base so that the line of action of its weight stays within the base when it goes around a sharp corner. If something has a high centre of mass combined with a small base then it is very unstable and will topple over with minimal effort.
A plumb line is an example of a simple pendulum. All it consists of is a weight attached to a piece of string that can swing freely. The time taken for it to swing from one side to the other and back again is called the time period. The time period of a pendulum of the same length is always the same no matter what height you release it from, which is what makes them so good at keeping time. The time period and the frequency are related by the formula: T = 1/f. So if a pirate ship at a theme park swung with a frequency of 0.2Hz then the time period would be 5s, which is one scary ride!

Center of mass
In physics, the center of mass of a distribution of mass in space is the unique point where the weighted relative position of the distributed mass sums to zero or the point where if a force is applied causes it to move in direction of force without rotation. The distribution of mass is balanced around the center of mass and the average of the weighted position coordinates of the distributed mass defines its coordinates. All forces are equal and opposite. Calculations in mechanics are often simplified when formulated with respect to the center of mass.
In the case of a single rigid body, the center of mass is fixed in relation to the body, and if the body has uniform density, it will be located at the centroid. The center of mass may be located outside the physical body, as is sometimes the case for hollow or open-shaped objects, such as a horseshoe. In the case of a distribution of separate bodies, such as the planets of the Solar System, the center of mass may not correspond to the position of any individual member of the system.

Center of mass (relativistic)
In physics, relativistic center of mass refers to the mathematical and physical concepts that define the center of mass of a system of particles in relativistic mechanics and relativistic quantum mechanics.
Introduction
In non-relativistic physics there is a unique and well defined notion of the center of mass vector, a three-dimensional vector (abbreviated: "3-vector"), of an isolated system of massive particles inside the 3-spaces of inertial frames of Galilei spacetime. However, no such a notion exists in special relativity inside the 3-spaces of the inertial frames of Minkowski spacetime.
In any rigidly rotating frame (including the special case of a Galilean inertial frame) with coordinates 
, the Newton center of mass of N particles of mass 
and 3-positions 
is the 3-vector
both for free and interacting particles.
In a special relativistic inertial frame in Minkowski spacetime with four vector coordinates 
a collective variable with all the properties of the Newton center of mass does not exist. The primary properties of the non-relativistic center of mass are

Center of Mass and stability demonstrations
It is useful to note that the mass-center is a fixed property for a given rigid body (e.g. with no slosh or articulation), whereas the center-of-gravity may, in addition, depend upon its orientation in a non-uniform gravitational field. In the latter case, the center-of-gravity will always be located somewhat closer to the main attractive body as compared to the mass-center, and thus will change its position in the body of interest as its orientation is changed.
In the study of the dynamics of aircraft, vehicles and vessels, forces and moments need to be resolved relative to the mass center. That is true independent of whether gravity itself is a consideration. Referring to the mass-center as the center-of-gravity is something of a colloquialism, but it is in common usage and when gravity gradient effects are negligible, center-of-gravity and mass-center are the same and are used interchangeably.

Script:
The centre of mass of an object is the point where the entire weight of an object appears to act. Working out the centre of mass of a symmetrical object is easy; it’s simply the point where the lines of symmetry cross.
However it’s very unlikely that you’ll be dealing with such perfect shapes so you work it out by suspending the object freely, along with a plumb line. The centre of mass is always below the point of suspension, so by marking the vertical along the plumb line you know the centre of mass is somewhere along that line. By suspending the object from another point and repeating the process, you get two lines that intersect and the point of intersection is the centre of mass.
The position of the centre of mass is very important when it comes to the stability of an object. For example, a double decker bus is built to have a very low centre of mass and a wide base so that the line of action of its weight stays within the base when it goes around a sharp corner. If something has a high centre of mass combined with a small base then it is very unstable and will topple over with minimal effort.
A plumb line is an example of a simple pendulum. All it consists of is a weight attached to a piece of string that can swing freely. The time taken for it to swing from one side to the other and back again is called the time period. The time period of a pendulum of the same length is always the same no matter what height you release it from, which is what makes them so good at keeping time. The time period and the frequency are related by the formula: T = 1/f. So if a pirate ship at a theme park swung with a frequency of 0.2Hz then the time period would be 5s, which is one scary ride!

In this video Paul Andersen explains how the center of mass of an object represents the average position of matter in an object. The center of mass of a system is a combination of all the objects within the system. As long as no external torque is applied to the system the center of mass will be conserved.

The centre of mass is always below the point of suspension, so by marking the vertical along the plumb line you know the centre of mass is somewhere along that line. By suspending the object from another point and repeating the process, you get two lines that intersect and the point of intersection is the centre of mass.
The position of the centre of mass is very important when it comes to the stability of an object. For example, a double decker bus is built to have a very low centre of mass and a wide base so that the line of action of its weight stays within the base when it goes around a sharp corner. If something has a high centre of mass combined with a small base then it is very unstable and will topple over with minimal effort.
A plumb line is an example of a simple pendulum. All it consists of is a weight attached to a piece of string that can swing freely. The time taken for it to swing from one side to the other and back again is called the time period. The time period of a pendulum of the same length is always the same no matter what height you release it from, which is what makes them so good at keeping time. The time period and the frequency are related by the formula: T = 1/f. So if a pirate ship at a theme park swung with a frequency of 0.2Hz then the time period would be 5s, which is one scary ride!

In this first of the four part series I will show you how to find the center of mass of an ill-regular, odd shaped object.
Center of mass
In physics, the center of mass of a distribution of mass in space is the unique point where the weighted relative position of the distributed mass sums to zero or the point where if a force is applied causes it to move in direction of force without rotation. The distribution of mass is balanced around the center of mass and the average of the weighted position coordinates of the distributed mass defines its coordinates. All forces are equal and opposite. Calculations in mechanics are often simplified when formulated with respect to the center of mass.
In the case of a single rigid body, the center of mass is fixed in relation to the body, and if the body has uniform density, it will be located at the centroid. The center of mass may be located outside the physical body, as is sometimes the case for hollow or open-shaped objects, such as a horseshoe. In the case of a distribution of separate bodies, such as the planets of the Solar System, the center of mass may not correspond to the position of any individual member of the system.
