For each of the practical situations draw a free body diagram showing the direction and (where possible) the magnitude of the forces acting on the objects. The mass of each object is provided.

i) a book resting on a table

ii) a mass suspended from two springs iii) a ball attached to the hand of a clock

iv) a toy car rolling down a slope at constant speed b) Explain how Newton's 1st, 2nd and 3rd Laws apply to each of these situations.

c) In each case, predict how the forces acting on the object and motion of the object would change if a larger mass had been used
