 When calculating acceleration, to find the change in velocity, you subtract the _____________________________ velocity from the __________________________________ velocity.
 Inertia varies depending on what?
 Two cars are trafveling along the same road at the same speed, but different velocities. Explain.
 A skater in a parking lot. Can she have a constant speed and changing velocity? Can she have a changing speed and constant velocity? Explain your answer.
 a Balanced forces
 b The mass of an object
 c Initial
Final  d Opposite directions at the same speed.
 e Yes
No
You can be changing direction at constant speed to produce changing velocity. Any change in speed results in a change in velocity.
