Change to an object's motion is caused by unbalanced forces acting on the object.

a. identify changes that take place when particular forces are acting

forceA force is an action that changes or maintains the motion of a body or object. Simply stated, a force is a push or a pull. Forces can change an object’s speed, its direction,…

b. predict the effect of unbalanced forces acting in everyday situations

c. describe some examples of technological developments that have contributed to finding solutions to reduce the impact of forces in everyday life, eg car safety equipment and footwear design

d. analyse some everyday common situations where friction operates to oppose motion and produce heat

e. investigate factors that influence the size and effect of frictional forces
