Chapter 4
 A good understanding of the concept of “work”.

Simple problems based on the relationship between force, distance and work:
Work

Force x Distance (Force & Distance are parallel or antiparallel)

Power as the rate at which work is done:
Power


Energy and its relationship to work. Different forms of energy: Elastic potential energy,
Gravitational potential energy and Kinetic energy.

Simple problems based on the following:
