1
Q
newton’s first law
A
an object at rest stays at rest and an object in motion stays in motion
2
Q
newton’s second law
A
greater acceleration requires greater force (COMPARISON)
3
Q
newton’s third law of motion
A
for every action there is an equal/opposite reaction
4
Q
conservation of momentum
A
if no net force acts on a system, then the total momentum of the system does not change
5
Q
elastic collision
A
when objects bounce off of each other
6
Q
inelastic collision
A
when objects stick together
7
Q
inertia
A
the tendency of an object to resist a change in motion
