Kinetic and Potential energy

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object possesses due to its motion. It depends on the mass of the object and the speed at which it is moving.

Front

What is potential energy?

Back

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

Front

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

Back

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

Front

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

Back

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

Front

What is the formula for 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 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

How does height affect potential energy?

Back

The higher an object is, the more potential energy it has, because potential energy is directly proportional to height.

Front

How does speed affect kinetic energy?

Back

Kinetic energy increases with the square of the speed; if speed doubles, kinetic energy increases by four times.

Front

What happens to kinetic energy as an object slows down?

Back

As an object slows down, its kinetic energy decreases.

Front

What happens to potential energy as an object falls?

Back

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