Potential and Kinetic 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 its velocity.

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state. It can be gravitational, elastic, or chemical.

Front

What is gravitational potential energy?

Back

Gravitational potential energy is the energy an object has due to its height above the ground and its mass.

Front

How is kinetic energy calculated?

Back

Kinetic energy (KE) is calculated using the formula: KE = 1/2 mv², where m is mass and v is velocity.

Front

What happens to potential energy as an object falls?

Back

As an object falls, its potential energy decreases while its kinetic energy increases, assuming no energy is lost to friction.

Front

What is the relationship between kinetic and potential energy?

Back

Kinetic and potential energy can transform into each other. For example, when an object falls, potential energy converts to kinetic energy.

Front

What is an example of kinetic energy?

Back

A tennis ball rolling across the court is an example of kinetic energy.

Front

What is an example of potential energy?

Back

The pulled back string on an archer's bow is an example of potential energy.

Front

What factors affect gravitational potential energy?

Back

Gravitational potential energy depends on the height and mass of the object.

Front

What type of energy does a person climbing a ladder have?

Back

A person climbing a ladder has both potential and kinetic energy.
