100
A machine cannot multiply this. Nothing can create or destroy this.
What is Energy?
100
Decay and steam.
What is the source of geothermal energy?
200
Kinetic energy is energy in_________.
What is motion?
200
In a waterfall, potential energy is transferred to this type of energy.
What is kinetic energy?
200
Energy cannot be created or destroyed. It can be transformed from one object to another. Energy never changes.
What is conservation of energy?
200
A machine can multiply these two factors.
What is Work and Distance?
200
Energy used to power windmills.
What is wind energy?
300
In order to give a ball more kinetic energy, you must do more ________. It is also measured in Joules.
What is Work?
300
This is the potential energy equation.
What is Weight x Height or Mass x 9.8 x Height?
300
A box sitting at the top of a ramp has 100J of Potential Energy. This is the amount of Kinetic Energy it has at the moment.
What is 0J?
300
These are two types of simple machines we discussed this chapter.
What is a lever and a pulley?
300
The primary energy source today.
What is Solar Energy?
400
This is the rate at which work is done. It is measured using Watts.
What is Power?
400
Plays a major role in Gravitational Potential Energy and is 9.8m/s squared.
What is gravitational acceleration?
400
Energy is never lost or created but it can be this.
What is transformed?
400
This is how you find out how much work output a machine is producing.
What is work input - heat energy lost?
400
Power plants create this type of energy.
What is Nuclear Energy?
500
This is the formula for Kinetic Energy.
What is 1/2 Mass x Velocity squared?
500
You are floating in your space suit about 1,000m from the earth's surface and your mass is 61kg. We had to use 9.8m/s squared since we know mass.
What is an example of using 597,800J as an answer for potential energy? acceptable answer: What is 597,800J?
500
When a box which has 100J of energy is sliding down a ramp and is 3/4 of the way down it has this much kinetic energy.
What is 75J?
500
This is the formula used to find a machine's efficiency.
What is work output/work input?
500
Dams create this type of energy.
What is hydroelectric power?
