Kinetic and Potential Energy

Front

What is Kinetic Energy?

Back

Kinetic Energy is the energy an object possesses due to its motion, calculated using the formula KE = 1/2 mv², where m is mass and v is velocity.

Front

What is Potential Energy?

Back

Potential Energy is the stored energy of an object due to its position or state, commonly gravitational potential energy, calculated using the formula PE = mgh, where m is mass, g is the acceleration due to gravity, and h is height.

Front

How do you calculate Kinetic Energy?

Back

Kinetic Energy (KE) is calculated using the formula KE = 1/2 mv², where m is the mass of the object and v is its velocity.

Front

What factors affect Gravitational Potential Energy?

Back

Gravitational Potential Energy depends on the height and mass of the object.

Front

At what point does a diver have the greatest Kinetic Energy?

Back

A diver has the greatest Kinetic Energy at the lowest point of their dive, just before entering the water.

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, demonstrating the principle of conservation of energy.

Front

What is the formula for Gravitational Potential Energy?

Back

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

Front

What type of energy does a moving skateboard represent?

Back

A moving skateboard represents Kinetic Energy.

Front

If an object is at rest, what type of energy does it have?

Back

An object at rest has Potential Energy, but no Kinetic 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.
