| Question | Answer |
|---|---|
| What is the ability to cause motion or create change? | energy |
| 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? | thermal energy |
| What type of energy is caused by the movement of electrically charged particles? | electrical energy |
| The transfer of heat that occurs when one thing touches another is called ______________? | conduction |
| The transfer of thermal energy in which warm air rises and moves cooler air downward is called _______________? | convection |
| Energy that is sent out in waves and can travel through matter and space is called ________________? | radiation |
| 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) |
| Give an example of how friction can create heat. | rubbing hands together creates heat; ice skates skating on ice can cause ice to melt due to heat (friction) |
| What type of energy is caused by vibrations that are carried by air, water, or other matter? | sound energy |
| The number of waves that pass a point in a certain amount of time is called _______________? | frequency of a wave |
| The distance between a point on one wave and a similar point on another wave is called_______________? | wavelength |
| _______________ is how high or low a sound is? | pitch |
| 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 of motion? | kinetic energy |
| What type of energy is energy that is stored? | potential energy |
| What type of energy travels as waves and can move through an empty space? | light energy |
| _______________ is when light passes through something and its speed changes, causing the light to bend. | refraction |
| When light bounces off or reflects from an object it is called _______________? | reflection |
| When an object absorbs light rays it is called _______________? | absorption |
