Down
- 2. total force on an object after all other forces have been combined
- 3. form of energy due to the total motion and arrangement of particles in a substance. also known as "heat" energy.
- 4. energy resources that exist in limited quantities and take millions of years to form.
- 6. length of a straight line from starting point to ending point of an object
- 7. form of energy that travels in waves. Has some magnetic properties and some electrical properties.
- 10. unit used to measure a force
- 13. occurs when the only force vertically acting on an object is gravity
- 18. energy resources that can be replaced in a short period of time
- 19. total length of path traveled by an object
- 21. an object in motion will stay in motion unless acted upon by an unbalanced force
