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 square of its velocity.

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 gravitational energy when an object is elevated.

Front

Where is potential energy maximum on a roller coaster?

Back

At the top of a big hill.

Front

What happens to potential energy as an object falls?

Back

As an object falls, its potential energy decreases while its kinetic energy increases.

Front

What is the formula for Kinetic Energy?

Back

Kinetic Energy (KE) = 1/2 mv², where m is mass and v is velocity.

Front

What is the formula for Potential Energy?

Back

Potential Energy (PE) = mgh, where m is mass, g is the acceleration due to gravity, and h is height.

Front

How does speed affect Kinetic Energy?

Back

The faster an object moves, the greater its kinetic energy, as it is proportional to the square of its speed.

Front

What type of energy is present in a stretched rubber band?

Back

Potential Energy, specifically elastic potential energy.

Front

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, assuming no energy is lost to friction.

Front

What is an example of Kinetic Energy in everyday life?

Back

A moving car, a flowing river, or a person running.
