Potential and Kinetic Energy

Front

What is the definition of kinetic energy?

Back

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

Front

What is potential energy?

Back

Potential energy is the stored energy of an object due to its position or state, often related to its height and mass.

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 factors affect potential energy?

Back

Potential energy is affected by the height of an object above a reference point and its mass.

Front

What is mechanical energy?

Back

Mechanical energy is the sum of potential energy and kinetic energy in a system.

Front

How does height affect potential energy?

Back

As the height of an object increases, its potential energy increases, assuming mass remains constant.

Front

What is the relationship between kinetic energy and velocity?

Back

Kinetic energy increases with the square of the velocity; if velocity doubles, kinetic energy increases by a factor of four.

Front

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.

Front

What is an example of kinetic energy in everyday life?

Back

A moving car, a flowing river, or a thrown ball are all examples of kinetic energy.

Front

What is an example of potential energy in everyday life?

Back

A book on a shelf, a drawn bow, or water stored in a dam are all examples of potential energy.
