Kinetic and Potential Energy

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object possesses due to its motion, which depends on its mass and velocity.

Front

What is potential energy?

Back

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

Front

How does the speed of an object affect its kinetic energy?

Back

The kinetic energy of an object increases with the square of its speed; as speed increases, kinetic energy increases.

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.

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.

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.

Front

What happens to kinetic energy as an object rises?

Back

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

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 the principle of conservation of energy?

Back

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