Physics Vocabulary

2. British scientist, Sir Isaac Newton (1624—1727) was able to state rules that described the effects of forces on the motion of objects. These rules are known as Newton's laws of motion.
3. For every action force there is an equal and opposite reaction force.
5. An object's resistance to a change in its motion. The greater the mass, the more it will resist a change in motion. More mass = more inertia.
9. The energy released during nuclear fission or fusion, especially when use to generate electricity.
12. The change in position over time.
13. An object in motion will stay in motion while an object at rest will stay at rest unless acted upon by an unbalanced force.
14. Applying a force to an object.
16. Energy that is produced through sound vibrations.
18. A course along which someone or something moves such as north, south, east, or west.
20. the ability to cause change
22. Energy that is stored or released through chemical bonds
23. The distance an object travels in a certain amount of time in a certain direction. (Speed with direction)
24. Force = Mass times Acceleration (F=ma)
25. Sum of potential and kinetic energy in a system. Energy of motion.
26. Energy that travels in the form of electricity.
27. Unit of Force

1. Forces on an object that are equal in size and opposite in direction. Results in a net force equal to 0N.
4. Energy that is released through heat.
6. Light energy given off by the Sun.
7. A change in speed or direction
8. The sum of two or more forces on an object that are pushing or pulling in the same or opposite direction.
10. The energy of a moving object has because of the motion.
11. Forces on an object that do NOT result in a net force equal to zero newtons.
15. A push or pull in a certain direction.
17. Stored Energy
19. The force applied to an object depends on the mass of that object and the acceleration that the object is moving at. F=MA
21. The distance an object travels in a certain amount of time.
