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 factors affect potential energy?

Back

Potential energy is directly proportional to mass and height. This means that as mass or height increases, potential energy increases.

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 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 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 relationship between mass and kinetic energy?

Back

Kinetic energy is directly proportional to mass. If the mass of an object increases, its kinetic energy increases as well.

Front

What is the relationship between speed and kinetic energy?

Back

Kinetic energy is proportional to the square of the speed. If the speed doubles, the kinetic energy quadruples.

Front

What is an example of potential energy?

Back

A rock held at the edge of a cliff has potential energy due to its height above the ground.

Front

What is an example of kinetic energy?

Back

A moving car has kinetic energy due to its mass and speed.

Front

How does height affect potential energy?

Back

The higher an object is, the more potential energy it has. For example, a ball held at 3 meters has more potential energy than one held at 1 meter.
