3. force that attracts a body toward the center of the earth, or toward any other physical body having mass.
5. 1st Law :An object at rest remains at rest, and an object in motion remains in motion at constant speed and in a straight line unless acted on by an unbalanced force
6. :a body's relative mass or the quantity of matter contained by it, giving rise to a downward force; the heaviness of a person or thing.
7. Motion:an object along the circumference of a circle or rotation along a circular
10. Pair :Two forces acting at the same point with equal magnitude but opposite direction
12. : the measure of the amount of matter in a body.
13. 3rd Law :or every action in nature there is an equal and opposite reaction
14. strength or energy as an attribute of physical action or movement.
16. force: any force that occurs as a result of two objects making contact with each other.
17. 2nd Law :the acceleration of an object is directly related to the net force and inversely related to its mass.

1. Forces :those that are opposite in direction and equal in size.
2. Force :a force that acts on a body moving in a circular path and is directed toward the center around which the body is moving.
4. :a tendency to do nothing or to remain unchanged.
8. of Conservation of Momentum : in an isolated system the total momentum of two or more bodies acting upon each other remains constant unless an external force is applied.
9. Force: objects do not have physical contact between them or when a force is applied without any interact
11. Force :the sum of all the forces acting on an object
14. :the resistance that one surface or object encounters when moving over another.
15. :the quantity of motion of a moving body, measured as a product of its mass and velocity.
