1.3 — Mass and weight

Core

• 1.3.1 — State that mass is a measure of the quantity of matter in an object at rest relative to the observer
• 1.3.2 — State that weight is a gravitational force on an object that has mass
• 1.3.3 — Define gravitational field strength as force per unit mass; recall and use g = W/m
• 1.3.4 — Know that weights and masses may be compared using a balance

Supplement

• 1.3.5 — Describe and use the concept of weight as the effect of a gravitational field on a mass
