Flashcard Review Potential and Kinetic Energy

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or configuration, often related to its height above the ground.

Front

What is kinetic energy?

Back

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

Front

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

Back

As an object falls, its potential energy decreases while its kinetic energy increases, conserving the total mechanical energy.

Front

At what point in a pendulum's swing is potential energy highest?

Back

Potential energy is highest at the highest points of the swing, where the pendulum is momentarily at rest.

Front

At what point in a pendulum's swing is kinetic energy highest?

Back

Kinetic energy is highest at the lowest point of the swing, where the pendulum is moving the fastest.

Front

What happens to potential energy on a roller coaster as it descends?

Back

As a roller coaster descends, its potential energy decreases while its kinetic energy increases.

Front

Where is maximum potential energy located on a roller coaster?

Back

Maximum potential energy is located at the top of a big hill on the roller coaster.

Front

Where is maximum kinetic energy located on a roller coaster?

Back

Maximum kinetic energy is located at the bottom of a big hill on the roller coaster.

Front

What is the formula for calculating kinetic energy?

Back

The formula for kinetic energy (KE) is KE = 1/2 mv², where m is mass and v is velocity.

Front

What is the formula for calculating potential energy?

Back

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