A slow jam is an umbrella term for music with R&B and Soul influences. Slow jams are commonly R&B ballads or downtempo songs. The term is most commonly reserved for soft-sounding songs with heavily emotional or romantic lyrical content. This definition has led to intense debate over whether particular songs should be classified as a "slow jam", e.g. Ginuwine's 1996 hit single "Pony". The common use and possible origin of this term traces back to 1983 when Solar Records group Midnight Star recorded the song "Slow Jam" on their album No Parking on the Dance Floor.

Asterisks (*) denote genres with variable tempos which constitute the use of dance music.

In kinematics, the speed of an object is the magnitude of its velocity (the rate of change of its position); it is thus a scalar quantity. The average speed of an object in an interval of time is the distance traveled by the object divided by the duration of the interval; the instantaneous speed is the limit of the average speed as the duration of the time interval approaches zero .

Like velocity, speed has the dimensions of a length divided by a time; the SI unit of speed is the meter per second, but the most usual unit of speed in everyday usage is the kilometer per hour or, in the USA and the UK, miles per hour. For air and marine travel the knot is commonly used.

The fastest possible speed at which energy or information can travel, according to special relativity, is the speed of light in vacuum c = 299,792,458 meters per second, approximately 1079 million kilometers per hour (671,000,000 mph). Matter cannot quite reach the speed of light, as this would require an infinite amount of energy. In relativity physics, the concept of rapidity replaces the classical idea of speed. In day-to-day athletics, it is proper to say that a teenager can achieve atleast 20 kmph (or 12.43 mph) of speed while a best runner can achieve 30 kmph (or 18.64 mph) which is similiar to run 100m running race in about 12 seconds. The average speed for a teenager is 24 kmph, which can be a result on running 100m in 15 seconds.

Fruit preserves are preparations of fruits, vegetables and sugar, often canned or sealed for long-term storage. The preparation of fruit preserves today often involves adding commercial or natural pectin as a gelling agent, although sugar or honey may be used, as well. Before World War II, fruit preserve recipes did not include pectin, and many artisan jams today are made without pectin. The ingredients used and how they are prepared determine the type of preserves; jams, jellies and marmalades are all examples of different styles of fruit preserves that vary based upon the ingredients used.

Many varieties of fruit preserves are made globally, including sweet fruit preserves, such as strawberry, as well as savoury preserves of culinary vegetables, such as tomatoes or squash. In North America, the plural form "preserves" is used to describe all types of jams and jellies. In British and Commonwealth English most fruit preserves are simply called jam, with the singular preserve being applied to high fruit content jam, often for marketing purposes. Additionally, the name of the type of fruit preserves will also vary depending on the regional variant of English being used.
