300
This renewable energy source involves plant materials and animal waste used as fuel.
What is biomass?
300
This simple machine increases distance to reduce the amount of force required to do work.
What is an inclined plane?
300
Describe the motion depicted below:
What is deceleration? (Slowing down)
300
A cyclist covers a distance of 2 miles in 5 hours. Calculate his speed.
What is 0.4 mi/hr?
300
According to this law, energy cannot be created or destroyed, it can only change forms.
What is the Law of Conservation of Energy?
400
Some power plants pump water down deep holes into hot rock. The hot rock heats the water, which turns the water into steam. The steam rushes back to Earth’s surface and is used to make electricity. This plant is generating which alternative energy resource?
What is geothermal?

In this type of energy source, uranium atoms are split apart and produce energy, which generates power.
what is nuclear power?
500
These two things make up a pulley
What is a wheel and axle?
500
Describe the motion in the following graph:
what is "constant speed, then deceleration"?
