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 is often associated with the height of an object above the ground.

Front

How is kinetic energy calculated?

Back

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

Front

How is potential energy calculated?

Back

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

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 kinetic energy?

Back

A car moving at 60 km/h is an example of kinetic energy.

Front

What is an example of potential energy?

Back

A stretched rubber band is an example of potential energy.

Front

What factors affect potential energy?

Back

Potential energy depends on the mass of the object and its height above the ground.

Front

What is energy transformation?

Back

Energy transformation is the process of changing energy from one form to another, such as potential energy converting to kinetic energy.

What happens to energy in a hydroelectric dam?

Back

In a hydroelectric dam, potential energy of water is converted into kinetic energy as it flows down, which is then transformed into electrical energy.
