Question 3.18: Describe one ‘Newton’s third law pair’ of forces involved in...
Describe one ‘Newton’s third law pair’ of forces involved in the following situations. In each case, state the object that each force acts on, the type of force and the direction of the force.
a You step on someone’s toe.
b A car hits a brick wall and comes to rest.
c A car slows down by applying the brakes.
d You throw a ball upwards into the air
a Force up on your foot and down on the footc that you tread on. Both forces are contact forces (normal reactions).
b Force backwards on the car and forwards on the wall. Both forces are contact forces (normal reactions).
c Backwards force on car and forwards force on ground. Both forces are frictional forces.
d Upwards force on ball and downwards force on your hand. Both forces are contact forces (normal reactions).
