Recall of Speed and Velocity

​

SPEED is how fast an object's position changes over time.

​

To calculate speed:

​Speed = distance ÷ time

Recall of Speed and Velocity

​

VELOCITY is the measurement that combines both the speed and the direction of a moving object.

​

To calculate velocity:

Velocity = speed + direction

​

​

​

​

Acceleration is the change in velocity over time for an object.​

​

​

To calculate acceleration, this equation will be used.​

Units of Acceleration:

1. cm/s²

2. m/s²​
