(a) state that mass is a measure of the amount of substance in a body
(b) state that mass of a body resists a change in the state of rest or motion of the body (inertia)

(c) state that a gravitational field is a region in which a mass experiences a force due to gravitational
attraction
(d) define gravitational field strength, g, as gravitational force per unit mass
(e) recall and apply the relationship weight = mass × gravitational field strength to new situations or to
solve related problems

(f) distinguish between mass and weight

(g) recall and apply the relationship density = mass / volume to new situations or to solve related
problems
