magnitude of velocity of motion

Speed is the distance of a moving object in a given amount of time. Speed is a measure of how fast something is moving. The average speed of an object in a certain time is the distance the object travelled divided by the time. Speed is also the distance covered by an object per unit time.

Finding speedEdit

To find speed  ,


where   is the distance and   is the time that has gone by.

Units of measurement for speedEdit

There are many units of measurement for speed. For example, an object's speed can be measured in

Changing speedEdit

When an object changes speed, it gets faster or slower. If the speed of the object increases, it is called acceleration. If the object gets slower, and the speed decreases, it is called deceleration, or negative acceleration.
