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 E = 1/2 mass x velocity².

Front

What is Potential Energy?

Back

Potential Energy is the stored energy of an object due to its position or state, often associated with gravitational force.

Front

What is the formula for calculating Kinetic Energy?

Back

E = 1/2 mass x velocity².

Front

What is the formula for calculating Gravitational Potential Energy?

Back

E = mass x gravity x height.

Front

What is the unit of energy in the International System of Units (SI)?

Back

The unit of energy is the Joule (J).

Front

How does height affect Gravitational Potential Energy?

Back

Gravitational Potential Energy increases with height; the higher an object is, the more potential energy it has.

Front

If a 100kg skydiver jumps from 4000 meters, how much gravitational potential energy do they have?

Back

3920000 J.

Front

What happens to Kinetic Energy as an object speeds up?

Back

As an object speeds up, its Kinetic Energy increases exponentially due to the velocity squared in the formula.

Front

At which point on a roller coaster is Potential Energy the greatest?

Back

Potential Energy is greatest at the highest point of the roller coaster.

Front

If a 6kg cat falls 5 meters, how much Gravitational Potential Energy does it have?

Back

294 J.
