One of Newton’s laws states that for every action, there is an ________ reaction.
unequal and opposite
equal and similar
stronger and opposite
equal and opposite
Gravity
The attraction any two objects with mass have on one another.
Newton’s 2nd law
A net force on an object causes it to accelerate with a magnitude proportional to the mass.
Momentum
The product of an object's mass and velocity.
The momentum of an object depends upon the object's ___________&_____________.
size and shape
mass and volume
mass and veloctiy
mass and energy

The Law of Conservation of Momentum states:
The total momentum before a collision is equal to the total momentum after a collision.
The total momentum before a collision is greater than the total momentum after a collision.
The total momentum before a collision is less than the total momentum after a collision.
The total momentum before a collision is not related to the total momentum after a collision.
How well do you understand these topics of forces and momentum?
Too easy! I totally get it.
It's okay, I mostly get it.
Ehhh, I'm struggling with some of the problems.
I do not get this at all.
