Kinetic and Potential Energy

Front

What is Kinetic Energy?

Back

Kinetic Energy is the energy an object possesses due to its motion. It is 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 energy stored in an object due to its position or state. The most common type is gravitational potential energy, calculated as PE = mgh, where m is mass, g is the acceleration due to gravity, and h is height.

Front

How do you calculate Gravitational Potential Energy?

Back

Gravitational Potential Energy (PE) is calculated using the formula PE = mgh, where m is mass (in kg), g is the acceleration due to gravity (approximately 9.81 m/s²), and h is height (in meters).

Front

At what point in a pendulum's swing is Kinetic Energy highest?

Back

Kinetic Energy is highest at the lowest point of the pendulum's swing, where the speed is greatest.

Front

At what point in a pendulum's swing is Potential Energy highest?

Back

Potential Energy is highest at the highest points of the pendulum's swing, where the height is greatest.

Front

What is the formula for Kinetic Energy?

Back

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

Front

If a 60 kg person is at a height of 74.8 m, what is their Gravitational Potential Energy?

Back

The Gravitational Potential Energy is 43982.4 J, calculated using PE = mgh.

Front

What happens to Kinetic Energy as an object slows down?

Back

As an object slows down, its Kinetic Energy decreases because it is directly proportional to the square of its velocity.

Front

What is the relationship between Kinetic Energy and mass?

Back

Kinetic Energy is directly proportional to mass; if the mass increases, the Kinetic Energy increases, assuming velocity remains constant.

Front

What is the relationship between Potential Energy and height?

Back

Potential Energy is directly proportional to height; as height increases, Potential Energy increases, assuming mass remains constant.
