Chapter 4: Mass Weight and Density
Mass and weight
Gravitational field and field strength
(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.
