2. The product of the component of a force along the direction of displacement and the magnitude of the displacement
4. A vector that represents the sum of two or more vectors
8. A quantity that measures the ability of a force to rotate an object around some axis
10. A description of how close a measurement is to correct or accepted value of the quantity measured
12. The tendency of an object to resist being moved
13. The mutual force of attraction between particles of matter
16. The motion of a body when only the force of gravity is acting on the body
17. A quantity as the product of the mass and velocity of an object
20. An explanation that is based on prior scientific research or observations and that can be tested

1. The energy associated with an object because of the position, shape, or condition of the object
3. The energy of an object that is due to the object’s motion
5. The total displacement divided by the time interval during which the displacement occurred
6. Force A force that acts on a surface in a direction perpendicular to the surface
7. Vector sum of all forces acting on an object
9. The perpendicular distance from the axis of rotation to a line drawn along the direction of the force
11. The energy of a substance due to the random motions of its particles
14. An action exerted on an object which may change the object’s state of rest or motion
15. The product of the force and the time over which the force acts on the object
18. The acceleration directed toward the center of a circular path
19. The concentration of matter of an object, measured as the mass per unit volume of a substance
