Kinetic and Potential Energy

Front

What is the definition of kinetic energy?

Back

Kinetic energy is the energy that an object possesses due to its motion, calculated as KE = 1/2 mv², where m is mass and v is velocity.

What is the definition of potential energy?

Back

Potential energy is the stored energy in an object due to its position or state, commonly associated with gravitational potential energy, calculated as PE = mgh, where m is mass, g is the acceleration due to gravity, and h is height.

What happens to kinetic 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.

What is the principle of conservation of energy?

Back

The principle of conservation of energy states that energy cannot be created or destroyed, only transformed from one form to another.

How does mass affect kinetic energy?

Back

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

How does height affect potential energy?

Back

Potential energy increases with height; the higher an object is positioned, the greater its potential energy due to the gravitational force.

What is the relationship between kinetic and potential energy in a closed system?

Back

In a closed system, the total mechanical energy (kinetic + potential) remains constant, as energy transforms between the two forms.

What is gravitational potential energy?

Back

Gravitational potential energy is the potential energy held by an object because of its height above the ground, calculated as PE = mgh.
