A push or a pull is called a
Gravity
Force
What is Newton's 2nd Law?
For every action there is an equal and opposite reaction.
Acceleration depends on two variables, the mass of the object and the amount of force.
What is Newton's 3rd Law?
For every action there is an equal and opposite reaction.
Acceleration depends on two variables, the mass of the object and the amount of force.
What explains why objects resist changes in their state of motion?
gravity
inertia
force
friction
What does the second part of Newton’s first law say about objects at rest?
They cannot move unless they have a lot of friction.
If they are heavy, they will stay at rest, but if they are light, they will move.
They will stay at rest unless an outside force makes them move.
They have more inertia than objects in motion.
