Physical Science

2. Inertia in motion
7. A phenomenon about which competent observers who have made a series of observations are in agreement
10. The collective findings of humans about nature, and a process of gathering and organizing knowledge about nature
11. Simply stated, a push or a pull
13. The quantity of space an object occupies
15. A synthesis of a large body of information that encompasses well-tested and verified hypotheses about certain aspects of the natural world
16. The vector sum of forces acting on an object that is not accelerating equals zero
17. A collision in which the colliding objects become distorted, generate heat, and may even stick together
19. The product of the force and the distance moved by the force
20. The scientific unit of force
21. The resistive force that opposes the motion or attempted motion of an object past another object
22. Falling without air resistance
23. Energy of motion
24. The force that supports an object against gravity
26. The action force and the reaction force that occur in an interaction
27. Being without a support force, as in free fall
28. The energy that matter possesses due to its position
29. The combination of all forces that act on an object
30. The property by which objects resist changes in motion

1. The net work done on an object equals the change in kinetic energy of the object
3. Terminal speed in a given direction
4. The quantity of matter in an object
5. The percentage of the work put into a machine that is converted into useful work output
