Module 3

4. - rate at which work is done
5. - the product of a force exerted on an object multiplied by the object's displacement.
7. - the transfer of heat energy in the form of electromagnetic waves
9. energy-energy associated with the motion and position of everyday objects
13. : An inclined plane wrapped helically around a wheel and axle
16. -A measure of how hot or cold an object is compared to a reference point.
20. - the process of heat transfer in fluids by the means of rising and falling currents of liquid or gas

1. - the transfer of heat energy from one solid to another through direct contact
2. : Any rigid bar that can be used to pry or lift.
3. Energy – stored energy
6. Machines: The six basic machines that all machines are composed of. Include: Pulley, Lever, Inclined Plane, Wedge, Wheel & Axle, and Screw
8. : Rope wound around a wheel system used for lifting objects.
10. Machines: Any machine that is made up of more than one simple machine.
11. of conservation of energy- energy cannot be created nor destroyed
12. - the transfer of thermal energy from one object to another because of a difference in temperature.
14. and axle : Simple machine composed of two round disks of different diameter, joined together so that work can be done.
15. heat – the amount of heat needed to raise the temperature of one gram of a material by one degree Celsius.
17. : Part of the lever around which the input arm and output arm rotate.
18. Energy – energy that is in motion
19. Energy – (heat) kinetic energy of particles
