SR 16 - STAAR Review 16: Energy Transformation

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object possesses due to its motion. It depends on the mass of the object and the speed at which it is moving.

Front

Where is kinetic energy the greatest in a roller coaster?

Back

Kinetic energy is greatest at the lowest point of the roller coaster, where the speed is highest.

Front

What is gravitational potential energy?

Back

Gravitational potential energy is the energy an object has due to its position in a gravitational field, typically related to its height and mass.

Front

What two factors does gravitational potential energy depend on?

Back

Gravitational potential energy depends on height and mass.

Front

At which position does a roller coaster cart have the most kinetic energy?

Back

The roller coaster cart has the most kinetic energy at the lowest point of the track.

Front

What is solar energy?

Back

Solar energy is the energy that comes from the sun, which can be converted into other forms of energy, such as electrical energy.

Front

What energy transformation occurs in solar panels?

Back

In solar panels, solar (radiant) energy is transformed into electrical energy.

Front

What happens when a crock pot is plugged in and turned on?

Back

When a crock pot is plugged in and turned on, electrical energy is transformed into thermal energy.

Front

What is thermal energy?

Back

Thermal energy is the energy that comes from the temperature of matter. It is the total kinetic energy of particles in an object.

Front

What is the law of conservation of energy?

Back

The law of conservation of energy states that energy cannot be created or destroyed, only transformed from one form to another.
