5.A measure of an object’s inertia; also a measure of the amount of matter in an object.
7.The force on a body due to the gravitational attraction of another body.
9.A collision in which the colliding objects become distorted and/or generate heat during the collision.
11.Friction, or drag, that acts on something moving through air.
15.The force that acts to resist the relative motion (or attempted) of objects or materials that are in contact.
16.Energy of position, usually related to the relative position of two things.
17.When one body exerts a force on a 2nd body, the 2nd body exerts an equal and opposite force on the first. This is Newton's ____ Law.
18.Force that completely balances the weight of an object at rest.
19.Any influence that tends to accelerate an object; a push or pull.
20.The property of an object or a system that enables it to do work.

1.Energy of motion.
2.Collision in which colliding objects rebound without lasting deformation or heat generation.
3.The ratio of output force to input force for a machine. Is its mechanical _____.
4.For an object resting on a horizontal surface, the upward force that balances the weight of the object.
6.Everybody continues in its state of rest, or of motion in a straight line at constant speed, unless it is compelled to change that state by a net force exerted upon it. This is Newton's ____ Law.
8.The energy due to the position or the movement of something.
10.Force per surface area where the force is normal to the surface.
12.The acceleration produced by a net force on a body is directly proportional to the magnitude of the net force, is in the same direction as the net force, and is inversely proportional to the mass of the body. This is Newton's ___ Law.
13.The combination of all the forces that act on an object.
14.A diagram showing all the forces acting on an object.
