Q8. Explain in your own words what action/reaction pair is acting to help you walk. Describe magnitudes and directions of these
two forces. Make a sketch that shows the forces as vectors, i.e. as arrows.
Q9. Explain the action/reaction pair that is acting to allow the rolling motion of the tires of a car.
Q10. Draw vectors on the objects in this figure to indicate the forces that are acting on them. Identify at least two action/reaction
pairs in the figure.
