What is 6 N?
Resistance to change
What is inertia?
Force is described as a ____________ or a ____________.
What is a push or a pull?

What is mass?
The sum of all forces acting on a object
What is net force?
A ball rolling across the turf is an example of this type of friction
What is rolling friction?
Newton's Third Law states that every action has an equal and ____________ reaction.
What is opposite?

What is 7 N?
The two things that affect the force of gravity are mass and this
What is distance?
This type of force will cause movement
What is unbalanced force or nonzero net force?
What is fluid friction?
The formula to solve for force
What is mass x acceleration?
The acceleration of a 50 kg car if a 100 N force acts on it
What is 2 m/s/s?
The measure of the force of gravity on an object
What is weight?

What is 5 N to the right?
Two ways to increase friction is to push two object harder together or do this
