Acceleration

Front

A roller coaster accelerates from an initial velocity of 6.0 m/s to a final velocity of 70 m/s over 4 seconds. What's the acceleration?

Back

16 m/s²

Front

A car starts from rest at a stop light and reaches 20 m/s in 3.5 s. Determine the acceleration of the car.

Back

5.7m/s²

Front

Acceleration is defined as the CHANGE in

Back

velocity divided by the time interval

Front

Does acceleration only occur when things speed up?

Back

False

Front

Do you have acceleration when walking in a straight line at a consistent speed?

Back

no

Front

As you walk you make a right turn. Do you have acceleration?

Back

yes

Front

Do you have acceleration when you start to slow down while walking?

Back

yes

Front

A drag racer accelerated from 0 m/s to 200 m/s in 5 s. What was the acceleration?

Back

40 m/s²

Front

Acceleration

Back

A change in Motion

Equation to solve: Car going 30 m/s slows to stop at -6.25 m/s².

Back

V_f = (a•t) + v_i
