12.2 KE and PE

Front

What is Potential Energy?

Back

Potential Energy is the energy possessed by an object due to its position or condition, such as an object at height or a compressed spring.

Front

What is Kinetic Energy?

Back

Kinetic Energy is the energy possessed by an object due to its motion.

Front

What factors affect Potential Energy?

Back

Potential Energy depends on mass and height.

Front

What factors affect Kinetic Energy?

Back

Kinetic Energy depends on mass and velocity.

Front

How is Potential Energy calculated?

Back

Potential Energy (PE) = mass (m) × gravitational acceleration (g) × height (h).

Front

How is Kinetic Energy calculated?

Back

Kinetic Energy (KE) = 1/2 × mass (m) × velocity (v)².

Front

What happens to Kinetic Energy when an object's speed doubles?

Back

If the speed of an object doubles, its Kinetic Energy increases by a factor of four.

Front

What is the Law of Conservation of Energy?

Back

The Law of Conservation of Energy states that energy cannot be created or destroyed, only transformed from one form to another.

Front

What is an example of Potential Energy?

Back

An example of Potential Energy is a book placed on a shelf.

Front

What is an example of Kinetic Energy?

Back

An example of Kinetic Energy is a moving car.
