Physics

1. a high force or shock applied over a short time period when two or more bodies collide.
3. a change in position of an object over time.
5. a scalar quantity that refers to "how much ground an object has covered" during its motion.
6. motion any type of motion when either the distance traveled by the object is the same for each second, or the speed of the object changes by the same amount each second.
9. the change of momentum of an object when the object is acted upon by a force
11. any interaction that, when unopposed, will change the motion of an object.
12. collision is one in which part of the kinetic energy is changed to some other form of energy in the collision.
13. is the rate of change of velocity of an object with respect to time.
14. is a physical vector quantity; both magnitude and direction are needed to define it.
15. the quantity of matter in a body regardless of its volume or of any forces acting on it.

2. it refers to the quantity of motion that an object has.
4. any object that once projected or dropped continues in motion by its own inertia and is influenced only by the downward force of gravity.
5. a vector quantity that refers to "how far out of place an object is".
7. the rate at which an object covers distance.
8. collision as one in which there is no loss of kinetic energy in the collision.
10. motion describes an object that is moving in a specific direction at a constant speed.
