Motion Section 3 Acceleration

Acceleration Measured in meters per second per second or m/s2 A change in speed is caused by: Acceleration – increasing speed Deceleration – decreasing speed negative acceleration - can change an objects direction Measured in meters per second per second or m/s2

Calculating Acceleration Acc. = Change in speed Time A car travels at 60m/s. It speeds up to 80m/s in 5 seconds. What is the acceleration?

Practice A roller coaster is moving at 35 m/s at the bottom of a hill. 4 seconds later at the top it is traveling 15 m/s. What is the deceleration?

Graphing Acceleration Speed vs. Time graph Slope is equal to the acceleration of the object. distance vs. time graph - a curved line means the object is accelerating. Speed time
