Force and Motion Review
Across
- 4. a machine is a machine made up of many simple and compound machines (like robots, cars, motocycles)
- 7. is the force that slows the motion of moving objects
- 9. energy is energy you can hear, which is produced when something vibrates
- 14. is the tendency of a moving object to stay in motion or a resting object to stay at rest
- 18. Energy that comes from chemical changes
- 19. the kind of energy an object has because it can move or because it is moving
- 20. is the ability to do work
- 21. These two things must happen for work to be done (2 words)
Down
- 1. __ energy is the energy of motion (going down the roller coaster)
- 2. When force is used on an object and it does not move, __ work is done.
- 3. energy (also known as thermal energy) is the amount of heat in an object
- 5. __ energy is energy that an object has because of position (sitting at the top of the rollercoaster)
- 6. is the result of a force moving an object
- 8. Newton The scientist that learned that a moving object will continue moving in a straight line until a force causes it to slow down or stop and that an object not rest will stay at rest until a force moves it
- 10. a push or pull on an object that can cause it to change motion
- 11. a machine made of one or two parts (like a lever or pulley)
- 12. a machine is a machine made of two or more simple machines (like scissors, bulldozer, or bike)
- 13. is the force that pulls two objects toward one another because of their mass and can be measured
- 15. is a machine that makes work easier
- 16. Energy that comes from the flow of electricity
- 17. energy is energy you can see
