When can one use the work energy theorem?
Work-Energy Theorem:
Mathematically, the work-energy theorem can be represented as:
Here,
is the final kinetic energy.
is the initial kinetic energy.
is the net work done.
According to the Work energy theorem,
Work done by all the forces = Change in Kinetic Energy
Here,
is the work done by gravity.
is the work done by a normal force.
is the work done by friction.
is the final kinetic energy.
is the initial kinetic energy.
