200

Give an example of something with mechanical energy, in other words potential and kinetic energy.

What is something moving and going up?

200

Name four different forms of energy (think about the poster, presentation we made)

Possible answers are: What is potential, kinetic, mechanical, chemical, solar, electrical, electromagnetic, nuclear, thermal, radiant.

300

What happens to kinetic energy if you double the mass of an object?

It doubles (multiplies by 2)

300

This is the point where a ski lift has the most potential energy

What is the top of the mountain/ski lift?

300

Will the skater go over the first bump, why or why not?


No, they will not have enough energy as they started too low.

300

If I turn on a lamp, what forms of energy is being transferred? There should be three.

Electrical to radiant/light and thermal.
