Energy Flashcard

Front

What is potential energy?

Back

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

Front

How does an archer demonstrate potential energy?

Back

By pulling back the bowstring, the archer stores potential energy in the bow.

Front

What happens to potential energy when an arrow is released?

Back

The potential energy is converted into kinetic energy as the arrow moves.

Front

Which object has more gravitational potential energy: a kite flying in the air or a car parked on a hill?

Back

A kite flying in the air has more gravitational potential energy due to its height.

Front

What type of energy does a stretched rubber band have?

Back

A stretched rubber band has potential energy.

Front

Define energy.

Back

Energy is the capacity to do work.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion, dependent on its mass and velocity.

Front

How is kinetic energy calculated?

Back

Kinetic energy (KE) is calculated using the formula KE = 1/2 mv², where m is mass and v is velocity.

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.

Front

Give an example of energy transformation.

Back

When a roller coaster descends from a height, potential energy is transformed into kinetic energy.
