Write your abstract
here.Mechanics deals with forces and their
effects
on the body on which they act.Forces causes a body to
change it's state of rest to a state of motion.There
are different types of forces depending on the number
of forces acting on a body and depending on the
direction
in which they act.Some of the foces act on a body in
the
same direction and some forces act in the opposite
direction.Some foces acts on a body at an angle.Forces
have magnitude and different forces have different
magnitudes.Force causes a body to move from one place
to another as a result work is done by the body.Energy
is the capacity of a body to do work.Potential energy
is the energy which a body has when it is at rest.
Kinetic energy is the energy that a body has when
it is in motion.Power is the rate at which work is
done.
Efficiency is measure of the amount of useful work
done by a body.The force applied on a body should be
fully utilised by the body in doing work for complete
effciency.Sometimes the force applied on a body is
is not fully utilised by the body it is wasted away
in the form of friction this leads to inefficiency.
