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.

What is motion?

• the location of an object

• the change in position over time

• distance divided by time

• the velocity of an object

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

What is acceleration?

• A change in position over time.

• The rate at which one quantity distance changes compared to another quantity time 

• The rate at which velocity changes

• A measure of how far something moves in a given amount of time.
