This is an example of Newton's ___ law of motion.
What is third?
Gravity and magnetism are examples of _______ forces, because they act on objects from a distance.
What are non-contact forces?

This is an example of Newton's ____ law.
What is second?
When the forces acting upon an object are unbalanced, the object will ____.

Force Pairs
This is the formula for calculating acceleration (without using Force or Mass).
(v2 - v1) / t
The small shopping cart on the left has exactly 1/2 the mass of the big shopping cart on the left. If we push both carts with the exact same amount of force, how does the acceleration of the small cart compare to the acceleration of the big cart?
It will accelerate at exactly half the rate of the big cart.
