2. 2.1 Mass & Weight2.1 Mass & Weight
1. Be able to distinguish between the mass and
weight of an object.
2. Know that the Earth is the source of a
gravitational field.
3. Describe, and use the concept of, weight as the
effect of a gravitational field on a mass.
3. 2.2 Density2.2 Density
1. Describe an experiment to determine the
density of a liquid and of a regularly shaped solid
and make the necessary calculation using the
equation:
density = mass / volume or d = m / v.
2. Describe the determination of the density of an
irregularly shaped solid by the method of
displacement, and make the necessary calculation.
4. 2.3 Effects of Forces2.3 Effects of Forces
1. Know that a force is measured in newtons (N).
2. Describe how forces may change the size, shape
and motion of a body.
3. Plot and interpret extension-load graphs and
describe the associated experimental procedure.

4. State and use Hooke’s Law and recall and use
the expression
force = constant × extension (F = k x)
5. Recognise the significance of the term ‘limit of
proportionality’ for an extension / load graph.
