Types of Energy
What is energy?
Energy is the ability to do work, to make things happen, and to cause changes.
What kind of energy is when electricity creates motion, light or heat and give an example
Electrical energy - television sets, computers and refrigerators use electrical energy.
What kind of energy come energy directly from the sun ?
solar energy
What energy is created by changing the energy of moving water into electricity.
water energy
What is the symbol for a bulb?
circle with an X
Can energy be created or destroyed?
No
What kind of energy is motion that is caused by gravity and give an example
gravitational energy - a pencil falling off a desk, a waterfall
Give me an example of how energy can be transferred
Thermal energy is transferred from the oven to the food as it heats up in the oven.
- Kinetic energy is transferred from one object to another when the two objects collide.
- Chemical energy from food is transferred to a person when they eat it.
What energy is created by changing the energy of moving wind into electricity using turbines?
wind energy
What is the symbol for a motor?
circle with a M
What is the amount of energy something has stored inside it because of it's position and give an example
potential energy - lights that are turned off, a car that is stopped, food before you eat it... etc
What kind of energy is audible (able to hear) energy and give me an example
Sound Energy - Ms K. yelling, car radio, speakers on a computer
Give me an example of how energy changes forms
Chemical energy inside batteries can change into electrical energy when you put it inside a flashlight, the electrical energy then changes into light energy.
- Solar energy can change into electrical energy with the use of solar panels.
- A heater uses electrical energy and changes it into thermal (heat) energy.
- When you turn a light on electrical energy is changing into light energy.
What energy is energy that comes from the sun?
solar energy
What is the symbol for 1 battery
1 short line and 1 long line
What is energy of an object in motion and give an example.
Kinetic Energy - riding a bike, watching TV, talking on the phone, eatting..etc
What kind of energy is heat energy and give me an example
Thermal Energy - fire, the sun
What kind of energy is from sources that will never run out and give an example
Renewable Energy - solar, wind, water, geothermal
What energy that comes from using natural materials like plants (for example - burning wood for a fire)?
Biomass energy
2 long lines and 2 short lines
What is energy stored in a substance that can be released by chemical reactions and give an example
Chemical Energy - eating food, gasoline in a car
What kind of energy is visible light energy and give an example
Light Energy - light bulb, fireflies, flashlight
What type of energy is from sources that there is only a certain amount of, more of it will not be made so it will eventually run out and give an example
nonrenewable energy - oil, petrol, coal, natural gas
What energy that is produced by hot rocks deep beneath Earth’s surface?
geothermal energy
