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 stored energy based on an object's position or state. It is the energy an object has due to its height or condition.

Front

What is the formula for Kinetic Energy?

Back

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

Front

What is the formula for Potential Energy?

Back

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

Front

At which point does an object have maximum Potential Energy?

Back

An object has maximum Potential Energy at its highest point.

Front

At which point does an object have maximum Kinetic Energy?

Back

An object has maximum Kinetic Energy at its lowest point or when it is moving the fastest.

Front

How does height affect Potential Energy?

Back

Potential Energy increases with height; the higher an object is, the more Potential Energy it has.

Front

How does speed affect Kinetic Energy?

Back

Kinetic Energy increases with speed; as an object's speed increases, its Kinetic Energy increases exponentially.

Front

What is the relationship between Kinetic and Potential Energy in a closed system?

Back

In a closed system, the total energy (Kinetic + Potential) remains constant, demonstrating the principle of conservation of energy.

Front

What happens to Potential Energy as an object falls?

Back

As an object falls, its Potential Energy decreases while its Kinetic Energy increases.
