For every action, there is an equal and opposite reaction.

For work to be done, this must occur.

This simple machine consists of a rope that fits into a grove in a wheel.

These are the two forms of energy.

This is the transfer of energy from one object to another because of temperature difference.

An object at rest stays at rest and an object in motion stays in motion unless acted on by an outside force.

Work = Force x Distance.

A boat moving through water is an example of this simple machine.

Energy sources fit into these two categories.

The thermal energy of an object depends on these three things.

F = m x a

Doing work at a faster rate requires more of this.

You use this type of simple machine to steer your car when you’re driving.

The acceleration due to gravity.

The type of engine used to power a steam engine.

A measure of the rate at which an object moves.

The unit for measuring work.

These simple machines have an input arm, output arm and a fulcrum.

A type of energy that involves fusion or fission.

This is a material that conducts thermal energy poorly.

The tendency of an object to resist a change in motion.

Power = Work/Time.

The number of times a machine increases an input force.

This states that energy cannot be created or destroyed; only transferred in a different form.

This is the amount of heat needed to raise the temperature of one gram of a material by one degree Celsius.
