From the list of words above, choose the one that corresponds to the definitions below.

1. A vector quantity; measured in the units of kg m/s2 (Newton) and described as a push or a pull. _________________________

2. A scalar quantity; the amount of matter in an object or the measurement of its inertia. ______________________________

3. States that the acceleration of an object is directly proportional to the magnitude of the net force, is in the same direction as the net force and is inversely proportional to the mass of the object. ______________________________

4. The force that changes with respect to changes in gravity; the measure of the effect of gravity on an objects mass. ______________________________

5. Explains that forces act in pairs, that they are equal in magnitude, opposite in direction and act on different objects. _________________________________

6. A type of force that acts to oppose the motion of objects or materials that are in contact with each other. ______________________________

7. Forces that are equal in magnitude and opposite in direction and act upon the same object.
__________________________________

8. The state of motion of an object when the net force on the object is zero, it is not accelerating, but is moving at a constant velocity. ______________________________

9. Sum of all the forces acting on an object. ______________________________

10. The rate of change of velocity with respect to time. ______________________________

11. Property of matter describing an objects resistance to change in its current state of motion. ____________________________

12. Describes the state of motion of an object when the net force on the object is zero and it is not moving. ______________________________

13. Explains that an object at rest will remain at rest, and/or an object that is in motion will travel at a constant velocity in a straight path unless a net force acts upon it. ______________________________

14. It is the attractive force exerted on every object by another object and is due to the objects mass and the distance between the objects. ______________________________

15. A state of balance. May appear that there is no change in this state. ___________________________________

16. Measures a change in momentum. __________________________________

17. A frictional force that opposes something moving through air.  ______________________________

18. A vector quantity; measured in the units of kg m/s and described as inertia in motion.
______________________________

19. A substance such as a gas or a liquid which can flow around/through another material.
______________________________

20. Condition of freefall toward or around the earth, in which an object experiences no support force (and exerts no force on a
scale) due to the frame of reference and the object having the same acceleration.     _____________________________
