Energy
Describe energy stores and transfers, conservation of energy, efficiency, and thermal insulation
What you'll learn
- 1
Imagine a ball sitting on a shelf. It has stored energy — like a coiled spring waiting to be released!
- 2
What kind of energy does a ball on a shelf have?
- 3
Drag the ball to different heights on the shelf. See how the stored energy changes!
- 4
A 2 kg ball is on a 5 m high shelf. How much gravitational potential energy does it have? (g = 10 N/kg)
- 5
A 3 kg ball is on a 4 m shelf. What is its GPE? (g = 10 N/kg)
- 6
Energy can't be made or destroyed — it only changes form. That's the law of conservation of energy!
- 7
What happens to total energy when a ball falls?
