states that an object in motion stays in motion unless acted upon by and unbalanced force; an object at rest stays at rest unless acted upon by an unbalanced force.

• Newton's First Law

• Newton's Second Law

• Newton's Third Law

of motion explains how acceleration, force, and mass are related. It says an object's acceleration depends on the mass of the object and the size of the force acting on it.

What is Newton's 1st law of motion?

• An object does not move and stays that way because of gravity.

• An object at rest stays at rest unless acted upon by an unbalanced force. An object in motion stays in motion unless acted upon by an unbalanced force.

• The amount of mass in an object

• A push or pull

.....................is a force that pulls objects together. On Earth, it is a force that pulls all objects to Earth's center.
