Potential vs. Kinetic Energy

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or state. It is the energy that 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 the speed at which it is moving.

Front

How are mass and height related to potential energy?

Back

Mass and height are directly proportional to potential energy. This means that as mass or height increases, potential energy also increases.

Front

What are some forms of energy?

Back

Some forms of energy include light, sound, heat, and motion.

Front

What happens to potential energy when 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 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 relationship between kinetic energy and mass?

Back

Kinetic energy is directly proportional to mass. If the mass of an object increases, its kinetic energy increases if the speed remains constant.

Front

Which ball has the most potential energy: A ball held at 3 meters, 2 meters, 1 meter, or resting on the ground?

Back

A ball held at 3 meters has the most potential energy because it is at the highest position.

Front

What is the relationship between kinetic energy and speed?

Back

Kinetic energy is directly proportional to the square of the speed. This means that if speed doubles, kinetic energy increases by a factor of four.

Front

What is an example of potential energy?

Back

An example of potential energy is a rock held at the top of a hill. It has the potential to roll down and convert that energy into kinetic energy.
