Discussion questions
Discussion
- What is the difference between mass and weight?
- Would you weigh more or less on the Moon? Would your mass change? Why?
- Why does gravity pull you toward the center of the Earth rather than sideways?
- If you were floating in deep space far from any planet, would you have mass? Weight?
Quick work-a-long
Vocabulary: mass, weight, gravity, force, planet, surface.
Try it: Research your weight on the Moon (about 1/6 of Earth weight). Calculate your Moon weight and your partner's. Discuss: your mass stays the same — so what changes?
