Potential and Kinetic Energy 2 P

Front

What is Potential Energy?

Back

Potential Energy is the energy stored in an object due to its position or state. It is the energy that has the potential to do work.

Front

What is Kinetic Energy?

Back

Kinetic Energy is the energy of an object in motion. It depends on the mass of the object and the speed at which it is moving.

Front

What is the formula for calculating Kinetic Energy?

Back

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

Front

What is the formula for calculating Potential Energy?

Back

Potential Energy (PE) = mass (m) * gravity (g) * height (h).

Front

What is Mechanical Energy?

Back

Mechanical Energy is the sum of Potential Energy and Kinetic Energy in a system.

Front

If an object has 300 J of Potential Energy at the highest point, what is its Potential Energy halfway down?

Back

150 J.

Front

If an object has 300 J of Potential Energy at the highest point, what is its Kinetic Energy halfway down?

Back

150 J.

Front

What happens to Potential Energy as an object falls?

Back

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

Front

What type of energy is present when weights are held over your head?

Back

Potential Energy.

Why does a metal chair leg feel colder than a plastic one?

Back

The metal leg conducts your heat away faster than the plastic.
