5 True/False Questions

1. sliding friction → happens when 1 object rolls over another

   True        False

2. kinetic energy → energy of motion; the faster an object moves, the more kinetic energy it has

   True        False

3. newton → objects resist a change in motion

   True        False

4. inertia → objects resist a change in motion

   True        False

5. unbalanced forces → net force doesn't equal zero, then object's motion changes

   True        False
