Potential & Kinetic

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or configuration. 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 square of its velocity.

Front

How is potential energy calculated?

Back

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

Front

How is kinetic energy calculated?

Back

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

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 or other forces.

Front

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

Back

In a pendulum, potential energy is highest at the highest points of the swing, while kinetic energy is highest at the lowest point of the swing.

Front

What is an example of potential energy in everyday life?

Back

An example of potential energy is a drawn bow, where the energy is stored in the stretched string.

Front

What is an example of kinetic energy in everyday life?

Back

An example of kinetic energy is a moving car, where the energy is due to its motion.

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

How does height affect potential energy?

Back

The higher an object is positioned, the greater its potential energy, as potential energy is directly proportional to height.
