Physics

4. is a physical vector quantity; both magnitude and direction are needed to define it.
6. is a form of energy that an object or a particle has because of its motion.
10. is an applied force to bring desired change to the position of the load.
15. implies that an object has moved, or has been displaced.
17. takes place when particles, each other and come near enough to interact and exert a mutual influence.
20. the rate of increase of speed or the rate of change of velocity
21. is a scalar quantity that refers to "how fast an object is moving".
22. a number expressing a property, quantity, or relation that remains unchanged under specified conditions.

1. also called gravitation
2. change with time of the position or orientation of a body.
3. product of the mass of a particle and its velocity.
5. stored energy.
7. is change, or the interval over which change occurs.
8. the absolute unit of force in SI.
9. the capacity for doing work.
11. "how much ground an object has covered" during its motion.
12. quantitative measure of inertia, a fundamental property of all matter.
13. is any interaction that, when unopposed, will change the motion of an object.
14. unit of work or energy in the SI.
16. measure of energy transfer that occurs when an object is moved over a distance by an external force at least part of which is applied in the direction of the displacement.
18. are the standard units of measurement.
19. are standards for measurement of physical quantities that need clear definitions to be useful.
