Energy calculations: KE + GPE

Question 1

What is GPE?

Answer 1

Gravitational Potential Energy is energy due to the height of an object

Question 2

GPE calculation (with units)

Answer 2

GPE (Joules) = mass (kg) x gravitational field strength (newtons/kg) x height (m)

Question 3

Gravitational field strength on Earth

Answer 3

10

Question 4

What is KE?

Answer 4

Kinetic Energy is movement energy

Question 5

Kinetic energy calculation (with units)

Answer 5

KE (Joules) = 0.5 x mass (kg) x velocity2 (m/s2)
