Potential and Kinetic Energy

Front

What is potential energy?

Back

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

Front

What is kinetic energy?

Back

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

Front

What is mechanical energy?

Back

Mechanical energy is the sum of potential energy and kinetic energy in an object that is used to do work.

Front

How is potential energy calculated?

Back

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

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 air resistance.

Front

What is an example of potential energy?

Back

A rock held at the top of a hill has potential energy due to its height.

Front

What is an example of kinetic energy?

Back

A moving car has kinetic energy due to its motion.

Front

What is radiant energy?

Back

Radiant energy is the energy of electromagnetic waves, such as light from the Sun.

Front

What is the relationship between potential and kinetic energy?

Back

Potential energy can be converted into kinetic energy when an object is set in motion by an external force.

Front

What is gravitational potential energy?

Back

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