Types of Energy
When an object is held in the air it has this.
What is potential energy?
A battery is this form of energy.
What is chemical?
An oven performs this energy transformation.
(ex. one type to another)
What is electrical to heat?
Sound moves in this.
What is waves?
These are 3 types of fossil fuels.
What are coal, oil and natural gas?
When an object is released from the air and begins falling it is called this.
What is kinetic energy?
A light bulb is this form of energy.
What is light or electrical?
A television performs this energy transformation.
What is electrical to sound and light?
The height of a wave is called this.
What is the amplitude?
Name one way energy from the wind could be used.
What is through a wind turbine?
When a roller coaster is at the top of the hill it has this type of energy.
What is potential energy?
The sun is what this form of energy.
What is solar or heat?
A radio performs this energy transformation.
What is electrical to sound?
Chemical to sound if it is powered through a battery.
This is the time it takes for two wave peaks to pass a single point.
What is the frequency?
This are some positives (pros) and negatives (cons) of using wind turbines for energy.
What is a positive is that they don't pollute but negatives are they are expensive, slightly noisy, could be dangerous to birds and bats and they can't be build everywhere.
When a roller coaster goes down the hill it has this type of energy.
What is kinetic energy?
The wind is this form of energy.
What is mechanical(movement) energy?
A blender performs this energy transformation.
What is mechanical and sound?
This is the space between two peaks or two tops of a wave.
What is the wavelength?
How is it possible to use water energy of you are not located close to the water?
What is the water energy could be transformed into electrical energy and carried along power lines.
When a truck hits a car at the bottom of a hill this will happen to the car.
What is the truck will transfer some energy to the car so the car will move and the truck will come to a stop?
What is light or heat?
A wind up toy performs this energy transformation/
What is chemical to mechanical?
If you are racing a toy boat across a pond this type of wave could cause the boat to move the fastest.
What is a wave with a high frequency?
This is why fossil fuels are considered "nonrenewable".
What is because they cannot be replenished? Once we have used all the fossil fuels, we cannot create more.
