Motion Vocab

3. a body is at rest or moving at a constant speed in a straight line, it will remain at rest or keep moving in a straight line at constant speed unless it is acted upon by a force
4. the rate and direction of an object's movement
5. length of the path between 2 points
7. not moving, stable
8. a push or a pull exerted on an object; a force is described by its strength and direction; F=M x A
11. when two bodies interact, they apply forces to one another that are equal in magnitude and opposite in direction
12. the tendency of an object to resist any change in motion; is dependent upon the object's mass
13. length of the path between 2 points in a particular direction
15. one force is greater than another, the forces are not balanced

1. the motion-opposing force exerted by surfaces when objects are in contact with each other; factors include surface conditions and mass
2. The force that pulls objects toward each other; factors include the objects' masses and distance apart
6. the amount of matter in an object
7. the time rate of change of the momentum of a body is equal in both magnitude and direction to the force imposed on it
9. does not change it's position with respect to it's surroundings with time
10. equal in size and opposite in direction
14. the rate of change of velocity per unit of time
