What is it
This form of energy can show how energy and motion are related, and can be used to move objects.
What is mechanical energy?
Force is
a push or pull
This form of energy allows us to see.
What is light energy?
The type of energy do you receive when you listen to the radio.
What is Sound energy?
conductor
allows the flow of electricity
Pulling a wagon across the floor is an example of this type of energy.
What is mechanical energy?
When the lamp produces light, it demonstrates that the lamp must have what type of circuit–
closed circuit
This form of energy allows plants to grow and life to survive on Earth.
what is Solar Energy?
List at least 3 types of energy used by a TV.
What is light energy, electrical energy, thermal energy, sound energy,
insulator
blocks the flow of heat or electricity
What is Sound energy?
what basic material is needed to build a circuit
needed: battery, wire,
extra: bulb, buzzer, switch
This form of energy causes the temperature of Earth to rise during the day and fall at night.
What is solar energy?
The thunder created by a strike of lightening is an example of this form of energy.
What is sound energy?
Clouds are visible to use because THIS form of energy is reflected off earth.
What is light energy?
All of the following EXCEPT one can show mechanical energy being used: a toaster, a flashlight, a swing, a toy car.
What is a flashlight?
Describe how a switch works.
A switch is made of materials that conduct electricity. When the switch is closed the energy flows through it. When the switch is open the energy cannot flow.
The earth would loose what form of energy if we did not have the Sun
light and thermal energy
This form of energy can be converted from solar energy, chemical energy, and mechanical energy to help power appliances throughout your home.
What is electrical energy?
If a plant is grown in the dark, it may not grow as quickly as a plant that is grown using this form of energy.
What is solar energy?
A water turbine turns with fast moving water to produce electricity. What form of energy is used and produced
mechanical to electrical
Describe the difference between an open circuit and a closed circuit
A closed circuit follows a path that allows electrical energy to flow through. There are no breaks in the path. An open circuit has breaks in the path and does not allow the electricity to flow.
What form of energy does wind and moving water both have in common
mechanical energy
MELTS
mechanical, electrical, light, thermal, sound
What happens to the a light bulb during an open circuit
light is off
