Answer:
When a hockey puck is at rest, the net force on it
(gravity and the support force) is balanced, so the puck
is in equilibrium.
Hit the puck (that is, apply an unbalanced force to it)
and the puck experiences a change in motion—it
accelerates.
Apply another force by striking the puck again, and the
puck’s motion changes again.
Answer:
The acceleration is equal to the net force divided by the mass. If the net force acting on an object doubles, its acceleration is doubled. If the mass is doubled, then acceleration will be halved. If both the net force and the mass are doubled, the acceleration will be unchanged.
