Force and Motion

4. the force that attracts a body toward the center of the earth, or toward any other physical body having mass
8. an object going at the same velocity per second
13. strength or energy as an attribute of physical action or movement
14. Forces that are equal in size but opposite in direction
16. to indicate the intensity of a gravitational field
17. frictional force air exerts against a moving object
19. force acting in one direction vs force acting in the opposite direction
22. the rate of change of velocity per unit of time
23. a course along which someone or something moves
25. the sum of all the forces acting on an object
26. a force that attracts any two objects with mass
27. occurring continuously over a period of time
29. withstand the action or effect of
30. a place where someone or something is located or has been put

1. increase in the velocity of a moving body
2. not impeded by or creating friction
3. the speed of something in a given direction
5. an amount of space between two things
6. two forces acting in opposite directions on an object, and equal in size
7. Forces that cause a change in the motion of an object
9. a property of matter- continues motion in a straight line, unless that state is changed by an external force
10. the resistance that one surface or object encounters when moving over another.
11. when an object is slowing down
12. the action or process of moving or being moved
15. he quantity of matter that a body contains
18. reduction in speed or rate
20. the speed of an object remains the same
21. the indefinite continued progress of existence and events in the past, present, and future regarded as a whole
24. move under the force of gravity only
28. the rate at which someone or something is able to move or operate
