Calculating Potential and Kinetic 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 m v², 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 as PE = mgh, where m is mass, g is the acceleration due to gravity, and h is height.

Front

What is the formula for calculating Kinetic Energy?

Back

KE = 1/2 m v²

Front

What factors affect Gravitational Potential Energy?

Back

Gravitational Potential Energy depends on the height of the object above a reference point and its mass.

What is the gravitational potential energy of an 85 kg mountain climber at the summit of a 6267 m volcano?

Back

5220411 J

How do you calculate the Kinetic Energy of a 10 gram ball rolling at 3 m/s?

Back

The Kinetic Energy is 45 joules.

Front

What is the relationship between mass and Kinetic Energy?

Back

Kinetic Energy increases with the mass of the object; doubling the mass will double the Kinetic Energy if velocity remains constant.
