What is combine?
Attractive force existing between all objects with mass.
What is gravity?
Discovered the laws of gravity and motion.
Who is Isaac Newton?
_____ force is a push or a pull on one object by another object that is touching it.
What is contact?
The result of a net force that does not equal zero that acts on an object.
What are unbalanced forces?
An object will not change its motion unless a force acts on it.
What is Newton's first law?
Forces acting on an object that do not cause the object to move.

What is Newton's third law of motion?
When forces act in the same direction, you can _____ add the forces together.
_____ is a contact force that resists the sliding motion between two objects that are touching.
What is friction?
As the amount of mass increases, the force of gravity between two objects _______.
What is increases?
Name 3 types of noncontact force.
What are electricity, magnetism, and gravity?
