Which of these is NOT an example of inertia?
While pushing a very heavy box, Derek notices that it was much harder for him to get the box to start moving than it was for him to get the box to continue to move once it had started. This is an example of which mechanics principle?
In the absence of an external force, a moving object will
A truck is traveling horizontally to the left. On the bed of the truck is a crate. When the truck starts to slow down, the crate on the (frictionless) truck bed starts to slide. In what direction could the net force be on the crate?
