What you need to know

State that mass is a measure of the quantity of matter in an object
State that weight is a gravitational force on an object due to a gravitational field
Calculate weight using W = mg
Know that g ≈ 10 N/kg at the Earth's surface
Distinguish between mass and weight: mass is constant everywhere; weight depends on g
Describe the use of a spring balance to measure weight and a beam balance to measure mass
Know that g varies on different planets and moons
