Calculating Speed

When an object is moving, we say it is in MOTION. When an object is not moving, we say it is STATIONARY or AT REST

Speed is the measure of how fast an object is travelling. All moving objects have speed. Speed can be calculated by using the formula below. The symbol for speed is 'v', which stands for VELOCITY, the speed in a particular direction. 

For rearranging this formula, there are two methods you could use:

Velocity is a vector quantity, meaning it has two aspects - it has a size and a direction. Speed is a scalar quantity, meaning it has a size, but no direction. 

The Triangle Method

The Cancelling Method
