Motion

2. quantitative measure of inertia
4. 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
6. supported so as to stay in a specified position
7. The rate at which an object is moving
11. an amount of space between two things
16. The rate of change of velocity per unit of time
17. Equal in size and opposite in direction
18. The time rate of change of the momentum of a body is equal in both magnitude and direction to the force imposed on it

1. When two bodies interact, they apply forces to one another that are equal in magnitude and opposite in direction
3. not moving or not intended to be moved
5. unless it is acted upon by a force
8. the moving of something from its place
9. a property of matter by which it continues in its existing state of rest or uniform motion in a straight line, unless that state is changed by an external force
10. The rate of an object's movement
12. One force is greater than another, the forces are not balanced
13. the action of one surface or object rubbing against another
14. a natural phenomenon by which all things with mass or energy, including planets, stars, galaxies and even light, are attracted to one another
15. energy as an attribute of physical action
