Acceleration Calculations
Acceleration Calculations Name ________________
Acceleration means a change in speed or direction. It can also be defined as a change in velocity per unit or time.
a = vf – vi where a = acceleration
time vf = final velocity
vi = initial velocity
t = time
Calculate the acceleration for the following data.
Initial Velocity
1. 0 km/hr
2. 0 m/s
3. 20 km/hr
4. 50 m/s
5. 25 km/hr
6. 100 m/s
7. 12 m/s
Final Velocity
24 km/hr
35 m/s
60 km/hr
150 m/s
1200 km/hr
50 m/s
6 m/s
Time
