|What are the 5 forms of energy?
|mechanical, electrical, light, thermal, sound
|What type of energy is caused by moving particles that you feel as heat?
|What type of energy is caused by the movement of electrically charged particles?
|The transfer of heat that occurs when one thing touches another is called ______________?
|The transfer of thermal energy in which warm air rises and moves cooler air downward is called _______________?
|Energy that is sent out in waves and can travel through matter and space is called ________________?
|Give an example of a fossil fuel that can create heat.
|oil, coal, gas (fossil fuel to heat)
|Give an example of how the color of an object can absorb light and create heat.
|a black tee shirt will absorb light and create heat; a blacktop/driveway will absorb light and create heat (light to heat)

|The distance between a point on one wave and a similar point on another wave is called_______________?
|_______________ is how high or low a sound is?
|The more vibrations an object has = higher __________ and higher__________?
|higher frequency and higher pitch
|The less vibrations an object has = lower __________ and lower __________?
|lower frequency and lower pitch

|What type of energy is energy that is stored?
|What type of energy travels as waves and can move through an empty space?
|_______________ is when light passes through something and its speed changes, causing the light to bend.
|When light bounces off or reflects from an object it is called _______________?
|When an object absorbs light rays it is called _______________?
