Vocabulary
This is the attractive force between all objects in the universe.
Gravity
Mixing baking soda and vinegar in a bottle with a cork in the top make the cork shoot out of the top after a few seconds. The chemical energy transferred into ____________.
Kinetic energy
Fossil fuels are burned to produce heat to make electricity. What harmful gas is produced and released in the atmosphere when we burn fossil fuels?
Carbon Dioxide or greenhouse gasses
When you pull back on a sling shot, what type of energy is stored in the angry bird?
Potential Energy
A ball resting at the top of a cliff has more potential energy than a ball resting on a table.
True
The ability to do work or make something move
Energy
When an archer pulls back on a bow to shoot an arrow, what type of potential energy does the bow have?
Elastic Potential Energy
Some cities that have large rivers nearby build dams to conserve the kinetic energy from water flow and transfer it into electricity. Are rivers renewable or non-renewable energy sources?
Renewable (Clean) Energy
A larger bird with more mass will have more potential energy to cause more damage to pigs. What is another way to increase potential energy if you haven't unlocked a bigger bird yet?
Pull back further on the slingshot to increase the elastic potential energy.
The law of conservation states that energy can be created and transferred from one form to another.
False
This is the term used to describe the speed of gravity (when speed of an object in motion is gradually increasing).
Acceleration.
Electric energy has to be generated by energy in motion that causes heat. This movement turns a ____________ that looks like a giant propeller.
Turbine
Wind farms are build with hundreds of windmills to capture the kinetic energy from the movement of wind to transform it into electricity. Is wind a renewable or non-renewable energy source?
Renewable
After releasing a sling shot, the bird starts to fly which means it has kinetic energy. What happens to the kinetic energy as the bird flies higher? (Increase/decrease)
Kinetic energy can be stored and used as electricity.
True
Energy that is stored or not in motion
Potential Energy
We as humans get our energy from the energy stored in the food we eat. Where does the energy originally come from?
The sun
Gas and oil in your car is burned to produce heat energy that powers the engine. The heat energy is converted into ___________ energy for your car to move. Gas and oil are both (renewable/non-renewable).
Kinetic energy/non-renewable
A bowling ball and a basketball are both dropped from the top of the ladder. Which ball will hit the ground first?
They will both hit at the same time because gravity makes all things accelerate at the same speed.
A person jumping from a bungie jump has both gravitational and elastic potential energy.
True.
Energy that is in motion
Kinetic Energy
Where does MOST of the energy go that we as humans get from food?
Lost as heat energy into the atmosphere (aka-why we sweat when we use more energy to move).
Solar panels trap heat energy from the ________ and transform the energy into electrical energy. This is an example of a renewable/non-renewable energy source.
Renewable
As the angry bird flies in the air after being released from the slingshot he goes higher. The gravitational potential energy _________ (increases or decreases)?
Increases
Hydro, wind, solar, and thermal energy are all considered clean, renewable energy sources.
False
