Definitions
energy
The ability to do work or cause a change
If one bulb goes out, the whole string of bulbs goes out (think of Christmas Lights)
Series circuit
(TRUE or FALSE) Energy is never destroyed
True, Energy cannot be created or destroyed, it can only change form
What type(s) of energy does batteries in a radio use?
Electrical energy changed into sound energy
What happens to two objects when one has a negative charge and one has no charge
They attract each other
Conductor
Material which allows electricity to move easily
All circuits must connect to these two types of charges
Positive and Negative
A moving car has potential energy
False
What type of energy does a bowling ball need to make a strike?
Kinetic Energy
A power-strip with a refrigerator and a fan plugged in would be known as what type of circuit
Series circuit
Elastic Energy
potential energy which comes from bending or stretching an object
What is an Electrical Current?
The flow of charged particles
rubber and plastic are the main insulators for wires
True
Name three types of energy used on a roller coaster
Kinetic, Potential, Mechanical, Electric
What type of energy is made from gravitational potential energy and kinetic energy
Mechanical Energy
Reflection
Send something back or off in a different direction
What must be true for something connected to a battery to be powered?
It must connect to both the positive and negative sides - no gaps
Batteries move particles from a negative side to the positive side, not the positive side to the negative side
True
What type of energy is created when an object collects lots of one type of + or - charge
Static electricity
How do eyeglasses work? How do they effect the light passing through them? (Use a vocab word)
They refract (bend) the light to make thing look larger/closer or smaller/father than they are
Parallel Circuit
Electric circuit involving more than one loop
Name 4 conductors and 4 Insulators
Mr. Hicks knows the answers
Turning ON a light switch will OPEN the electrical circuit
False
What type of energy is slowly lost as an electrical current continues to move
Heat energy
Clark Industries and Nada Worldwide have teamed up to create a battery-powered skateboard which rolls faster than a car and has a headlight and a horn. Name 4 types of energy associated with their product
Kinetic, Electrical, Sound, Light, Heat
