In this chapter we will introduce the following concepts:
Kinetic energy of a moving object
Work done by a force
Power
In addition we will develop the work-kinetic energy ... theorem and apply
it to solve a variety of problems
This approach is alternative approach to mechanics. It uses scalars
such as work and kinetic energy rather than vectors such as velocity
and ... kinetic energy K = 1J

If a force F is applied to an object of mass m it can accelerate it and increase
its speed v and kinetic energy K. Similarly F can decelerate m and decrease...
