Acceleration

Acceleration Measures the change in an object’s velocity over time Units include a distance and a time squared Ex: mi/hr2, m/s2

Types of Acceleration: Same Direction of Motion AKA “Speeding Up” + = A force is applied in the same direction causing the bike to speed up.

Types of Acceleration: Opposite Direction of Motion AKA “Slowing Down” + = A force is applied in the opposite direction causing the bike to slow down.

Types of Acceleration: At angle to motion AKA “Turning” + = A force is applied at an angle causing the bike to change direction. The speed may not change!

Calculating Acceleration Must know: Final velocity (speed) Initial velocity (speed) Time A = velocity final – velocityinitial time
