Across
- 2. force - Force needed to move the obj that distance
- 7. wheel and axle with a rope moving it number of wheels
- 9. advantage - the number of times a machine multiplies force output force input force
- 14. distance-Distance that an object is moved by the person
- 16. Law of _________ of energy Energy cannot be created or destroyed only changed.
- 18. energy-energy of moving charged particles in an atom.
- 21. energy the sum of the Potential & Kinetic energy
- 22. energy- the energy exherted by the movement of molecules
- 23. distance-Distance the simple machine moves it
- 25. energy the release of energy by breaking or combining atoms.
- 26. energy- waves that only travel through matter
- 27. Mechanical advantage - IMA - a measurement of the calculated expected increase in force(this doesn't take into account friction)
Down
- 1. a force being moved a. distance W=fxd
- 3. energy- energy stored by gravity or Springs PE=mgh
- 4. tendancy of a system to go from Order to chaos. From concentrated to Spread out.
- 5. machine anything that lessens the amount of force needed to do work
- 6. and axle - 2 wheels rotating on a bar diameter Wheel diameter divided by diameter of Axle
- 8. - bar that rotates on a fixed point (fulcrum) input length output length
- 10. energy-Energy that travels in waves light, radio, wifi, tv etc.
- 11. force - Force in Newtons the person is exherting
- 12. Mechanical Advantage- AMA a measurement of the increase in force you get from a simple Machine.
- 13. energy- the energy an object has due to motion KE=m²
- 15. the ability to do work
- 17. potential energy-Energy stored by the Compresson or pull on a a flexible object (rubber ball, rubber band, Spring)
- 19. plane- ramp that in creases distance With slope In (axe, wedge, ramp)
- 20. energy. Energy stored in Chemical bonds and released in Chemical reactions.
- 24. = Output force (usually >1) input force
