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
