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 square of its velocity.

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state. It can be converted into kinetic energy when the object moves.

Front

Where is kinetic energy greatest in a tossed baseball?

Back

At the lowest point of its trajectory, where it is moving the fastest.

Front

Where is kinetic energy least in a tossed baseball?

Back

At the highest point of its trajectory, where it momentarily stops before falling.

Front

What is the principle of conservation of energy?

Back

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

Front

What type of energy does a microwave use?

Back

Electrical energy.

Front

How do nuclear power plants generate energy?

Back

They generate energy through the process of nuclear fission, where atomic nuclei split to release energy.

Front

What happens to potential energy as a rock falls from a cliff?

Back

The potential energy decreases as the kinetic energy increases.

Front

What is fission?

Back

Fission is a nuclear reaction in which the nucleus of an atom splits into smaller parts, releasing a large amount of energy.

Front

What is the relationship between mass and kinetic energy?

Back

Kinetic energy increases with an increase in mass, assuming velocity remains constant.
