Forms of Energy
All the energy something has due to its movement and position
What is mechanical energy?
A student is constructing an electrical circuit. Which of the following can provide energy for the circuit? A. Battery B. Wire C. light bulb D.buzzer
What is A. Battery
The pool cleaner's handle appears broken and bent when I look at it from outside of the pool. Why is that?
What is refraction?
The type of energy do you receive when you listen to the radio.
What is Sound energy?
Campfires can be used to cook food. What type of energy is being used?
What is thermal?
Pulling a wagon across the floor is an example of this type of energy.
What is mechanical energy?
Explain how a switch works in an electrical circuit.
When the switch is on the circuit is closed so electricity can flow. When the switch is off the circuit is open so electricity cannot flow.
Light travels in a straight line unless it is blocked by something. True or False
What is true?
List at least 3 types of energy used by a TV.
What is light energy, electrical energy, thermal energy, sound energy,
Electricity can only flow when there is...
What is a complete path?
Energy resulting from the flow of electric charge through a conductor
What is Electric energy?
In a parallel circuit electricity has ______ path(s) to follow.
multiple
Light bounces off of a smooth or shiny surface
What is reflection?
The thunder created by a strike of lightning is an example of this form of energy.
What is sound 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?
If one load stops working in a series circuit what happens to any other loads in the circuit?
They also stop working.
How does light travel?
What is in a straight line?
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?
Are the wires in a circuit an insulator or a conductor?
What is a conductor?
Burning coal and creating steam which then turns a turbine, is an example of this form of energy transforming into another form of energy (list both forms).
What is thermal energy transformed into mechanical energy?
If all the loads of a robot were wired in a series circuit, what would happen if the one of the lightbulb's in the robot burned out?
All the loads of the robot would not work because the electricity only has one path to follow in a series circuit.
What form of energy is used when plugging in a lamp?
What is Electric, Thermal, and Light energy?
When a scientist did an experiment on how to convert electrical energy to sound energy, he did not receive consistent results,. He should do THIS with his experiment to see if his results were correct.
What is repeating the experiment?
If you connect the wires of an electric circuit to a piece of jewelry why would the lightbulb in the circuit still turn on?
Because the jewelry is made of something that can conduct electricity.
