Circuits
What shape does a circuit typically resemble?
A circle or square
A ball has this type of energy at the top of a hill
Potential Energy
This type of heat transfer moves energy through space
An example: heat from the sun
Radiation
You are on your bike at the top of a hill, what type of energy do you have
potential energy
The force that keeps everyone and everything on earth from floating away
Gravity
A material that allows energy to pass through it is called this
Conductor
A ball rolling down a hill has this type of energy
Kinetic Energy
This type of heat transfer heat directly from one object to another.
An example: a metal spoon heating up when placed in hot water
Conduction
You are riding your bike down a hill, what type of energy do you have
What four forces have we talked about during this unit?
Push, pull, friction, and gravity
Rubber, plastic, and wood are all examples of this because they do not let electricity flow through them.
Insulator
The type of energy a circuit uses
Electric
This type of heat transfer occurs in cycles in liquids and gases.
An example: boiling water
Convection
When you jump into the air, this force brings you back down.
Gravity
On object NOT in motion is called what?
stationary
In a closed circuit, power is
a) able to flow
b) not able to flow
a) able to flow
Sound energy travels in
Invisible waves
A student heated a pot of soup on the stove. While stirring the soup with a metal spoon, the student noticed the spoon became very warm.
What is the most likely reason the spoon became warm?
a) the stirring action heated the spoon
b) warm air in the room heated the spoon
c) heat from the soup was transferred to the spoon
d) the student's hand transferred heat to the spoon
c
You pull a rubber band, what type of energy does it have
Elastic potential energy
Push
This part of a circuit can turn the flow of electricity on or off
This type of energy is produced by vibrating objects and allows us to hear
Sound energy
A lamp changes electrical energy into these two types of energy.
Heat energy and light energy
When you roll a ball on a grassy field, it slows to a stop because of this type of force.
Friction
Think back to our collision experiment:
What happens to the energy when a stationary object and a moving object collide?
Bonus 100 for using the correct vocabulary
The kinetic energy from the moving object is transferred to the stationary object.
