Potential and Kinetic Energy

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or state. It 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 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 height.

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.

Front

What is an example of potential energy?

Back

A book on a shelf has potential energy because of its height above the ground.

Front

What is an example of kinetic energy?

Back

A moving bicycle has kinetic energy because it is in motion.

Front

When does an object have maximum potential energy?

Back

An object has maximum potential energy at its highest point.

Front

When does an object have maximum kinetic energy?

Back

An object has maximum kinetic energy just before it hits the ground after falling.

Front

What is the relationship between potential and kinetic energy?

Back

Potential energy can be converted into kinetic energy and vice versa, depending on the object's motion and position.
