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 the equation W g = m and know that this is equivalent to the acceleration of free fall
• 1.3.4 Know that weights (and masses) may be compared using a balance
