What is energy?
The ability to do work or cause change.
Give an example of energy that we use every day.
Ex: Light energy, electrical energy, thermal energy, chemical energy
What are the two types of charge an object can have?
Positive and negative
What is potential energy?
Energy that is stored in an object that is not moving.
Two objects bump into one another and energy is transferred from one to the other.
What would happen if two positively charged object were placed near each other?
What is kinetic energy?
Energy of a moving object.
Give an example of heat being transferred between two objects.
Ex: Stove to a pan
Name a good conductor and tell why it is a good conductor.
Give an example of energy being transferred from one object to another.
Ex: The energy of one domino is transferred to the next as they fall.
Name three sources of light energy.
The sun, flashlight, light bulb.
Name a good insulator and tell why it is a good insulator.
Plastic because it does not allow electricity to pass through it easily.
Give an example of energy being transformed from one kind of energy into another.
Ex. Kinetic energy is transformed into sound energy as a basketball bounces off the gym floor.
What happens to the particles of an object when heat is transferred to them.
They speed up.
What does a resistor do in a light bulb?
It controls the flow of electricity so that it is transformed into light energy.
