Mass vs Weight

Distinguish between mass (amount of matter, measured in kg) and weight (gravitational force, measured in N), use the equation weight = mass × gravitational field strength, and explain why g differs on other planets and stars

Try this together

If your child weighed themselves on bathroom scales and was then asked what they would weigh on the Moon, could they explain the difference between mass and weight and work out a rough answer?
