Front

What is potential energy?

Back

Potential energy is stored energy that has the potential to do work due to an object's position or state.

Front

Where is gravitational potential energy highest?

Back

Gravitational potential energy is highest at the highest point in a gravitational field.

Front

What happens to potential energy as an object falls?

Back

As an object falls, its potential energy decreases while its kinetic energy increases.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion, calculated as 1/2 mv², where m is mass and v is velocity.

Front

At which points in a pendulum's swing is potential energy greatest?

Back

Potential energy is greatest at the highest points of the swing.

Front

At which point in a pendulum's swing is kinetic energy greatest?

Back

Kinetic energy is greatest at the lowest point of the swing.

Front

What is the relationship between potential and kinetic energy in a pendulum?

Back

In a pendulum, potential energy converts to kinetic energy and vice versa as it swings.

Front

What is the formula for calculating gravitational potential energy?

Back

Gravitational potential energy (PE) is calculated using the formula PE = mgh, where m is mass, g is acceleration due to gravity, and h is height.

Front

What is the effect of height on potential energy?

Back

The higher an object is, the more potential energy it has due to its position in a gravitational field.

Front

What is the minimum gravitational potential energy?

Back

The minimum gravitational potential energy occurs at the lowest point in a gravitational field.
