Motion Speed Acceleration

Which of the following is NOT an example of acceleration?

• Driving at a steady speed and turning left.

• Driving at a steady speed and then slowing down.

• A change in velocity from 40km/h to 65 km/h

• A car moving at a steady speed of 60 km/hr.

How do you calculate average acceleration of an object?

• Subtract the final velocity from the initial velocity and divide by time

• Subtract the initial velocity from the final velocity and divide by time

• Add the the two distances and divide by the total time

• Divide distance by time

The rate at which velocity changes is called?

• Speed

• Acceleration

• Position

• Motion

Calculate the average acceleration of a car given the following information:

Initial velocity 10 m /sec   
Final velocity  55 m /sec 

The change in velocity took 3 seconds 

• 18.33 meters per second squared 

• 21.67 meters / second squared 

• 15 meters / second squared
