• The inertia is changing
• The inertia of the car is too great

Inertia refers to ___________

(select all the apply)

• the tendency of moving objects to remain in motion

• the force which keeps moving objects in motion with a constant velocity

• the force that keeps stationary objects at rest

• the tendency of stationary objects to remain at rest

A skateboard rolls down a hill, reaches the level surface and eventually comes to a stop. The fact that the skateboard ultimately stops is best explained by ________.

• the skateboard needs an additional unbalanced force to continue its motion

• the presence of an unbalanced force can cause a moving object to stop

• the presence of inertia causes it to stop

• the natural tendency of any object is to stop at some point
