U6P: Energy Storage and Transfer Model

Front

What is potential energy?

Back

Potential energy is stored energy based on an object's position or state.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion.

Front

How do you calculate gravitational potential energy?

Back

Gravitational potential energy = mass × acceleration due to gravity × height.

Front

What is the definition of power in physics?

Back

Power is the rate at which energy is transferred or work is done.

Front

What happens to energy when friction is present?

Back

Friction transforms kinetic energy into thermal energy.

Front

What is the relationship between mass and gravitational potential energy?

Back

Gravitational potential energy increases with greater mass.

Front

How does height affect gravitational potential energy?

Back

Gravitational potential energy increases with greater height.

Front

What is the formula for kinetic energy?

Back

Kinetic energy = 0.5 × mass × speed².

Front

What is the unit of energy in the International System of Units (SI)?

Back

The unit of energy is the Joule (J).

Front

What is the principle of conservation of energy?

Back

Energy cannot be created or destroyed, only transformed from one form to another.
