This section provides knowledge and understanding of Forces, what a force is and the effects of a force.

Engineers analyse forces when designing a great variety of machines and instruments, from road bridges and fairground rides to atomic force microscopes. Anything mechanical can be analysed in this way. Recent developments in arti cial limbs use the analysis of forces to make movement possible.

The different areas of this topic are outlined here;

Contact and non-contact forces

Centre of mass (COM)

Resultant forces

Resolving forces

Hooke’s law

Work done and the definition of the joule

Pressure

Pressure at different depths

How the atmosphere changes at different heights

Moments and turning forces

Speed, velocity, distance, displacement and relative speed of objects

Distance-time graphs

Velocity-time graphs

Acceleration

Equations of motion

Newtons 1st law

Newtons 2nd law

Newtons 3rd law

Thinking distance, braking distance and stopping distance

Reaction time, thinking time and braking time

Momentum

Conservation of momentum

Force as a rate of change of momentum

Please remember that you started your GCSEs in year 9 and also learnt material in years 7 and 8 which led into this topic.
