Physics

5. An action exerted on an object which may change the object's state of rest or motion
7. The motion of a body when only the force due to gravity is acting on the body
8. The energy transferred between objects because of a difference in their temperatures
10. A vector that represents the sum of two or more vectors
12. The perpendicular distance from the axis of rotation to a line drawn along the direction of the force
15. A force that acts on a surface in a direction perpendicular to the surface
17. The change in position of an object
18. The concentration of matter of an object, measured as the mass per unit volume of a subtance
20. The sum of kinetic energy and all forms of potential energy

1. The upward force exerted by a liquid on an object immersed in or floating on the liquid
2. The product of the force and the time over which the ofrce acts on an object
3. The rate at which velocity changes over time
4. The tendency of an object to resist being moved or, if the object is moving, to resist a change in speed ir direction
6. A physical quantity that has both magnitude and direction
9. A set of particles or interacting components considered to be a distinct physical entity for the purpose of study.
11. A measure of the average kinetic energy of the particles in a substance
13. A quantity defined as the product of the mass and velocity of an object
14. The product of the component of a force along the direction of displcement and the magnitude of the displacement
16. A description of how close a measurement is to the correct or accepted value of the quantity measured
19. A quantity that measures the ability of a force to rotate an object around some axis
