-
- Pupils should develop their knowledge and understanding of forces;
- their nature, significance and effects on the movements of objects.
-
- Level 1 * know that things can be moved by pushing them.
-
- Level 2 * understand that pushes and pulls can make things start
- moving, speed up, swerve, or stop.
-
- Level 3 * understand that when things are changed in shape, begin to
- move or stop moving, forces are acting on them.
-
- * understand the factors which cause things to float or sink
- in water.
-
- Level 4 * understand that the movement of an object depends upon the
- size and direction of the forces exerted on it, for example,
- in the context of investigations with elastic and wind
- powered models.
-
- * understand that the greater the speed of an object the
- greater the force and/or time that is needed to stop it and
- understand the significance of this for road safety.
-
- * understand that things fall because of a force of attraction
- towards the centre of the Earth.
-
- * be able to recognise that weight is a force, and know that
- it is measured in newtons.
-
- Level 5 * understand that when an object is not moving relative to its
- environment, or when it is moving at a steady speed without
- change in direction, there are balanced forces acting upon
- it, for example a car standing at rest on the surface of the
- Earth.
-
- * be able to give an account of an investigation of the
- strength of a structure.
-
- * be able to measure forces, distance and time.
-
- * be able to describe the effects of friction on moving
- objects.
-
- Level 6 * be able to calculate speed from direct measurements of
- distance and time.
-
- * understand the relationship between applied force, the area
- over which it acts and the resulting pressure.
-
- * understands that the effect of a turning force depends on
- where it is applied in relation to pivot and its line of
- action.
-
-
-
- Level 7 * be able to give simple qualitative explanations of the
- effects in everyday situations involving force, pressure,
- friction, mass, velocity and acceleration.
-
- * be able to evaluate the design of a structure or artefact,
- by balancing considerations of strength, choice of material
- and cost.
-
- Level 8 * understand the concept of centre of mass and apply it in
- practical circumstances.
-
- Level 9 * understand and apply the mathematical relationship between
- force, mass and acceleration.
-
- * understand the difference between mass and weight and
- between potential and kinetic energy.
-
- Level 10 * be able to recognise the interrelatedness of the ideas given
- in level 9 and apply them quantitatively in new situations.
-
- * understand the concept of momentum and how it differs from
- energy.
-
- * understand qualitatively, that circular motion requires a
- centripetal force.
-
- * be able to determine the relationships between forces and
- their effects when testing a structure or artefact.
