Recall that a force is a push or pull
Describe that balanced forces mean an object is stationary or moving at a steady speed.
Know that forces are measured in Newtons.
Recall that a Newton meter can be used to measure forces.
Explain using forces why a boat floats or sinks
Define and calculate density
Describe mass and weight and the difference between them.
Know the units for mass and weight.
Explain how weight varies depending on gravitational field strength and so will vary depending on where in
the solar system you are e.g. the Moon.
Explain friction
Give the advantages and disadvantages of friction
