Turning Points
For conservative forces, the
mechanical energy of the system
is conserved and given by,
U(x) + K(x) = Emec
where U(x) is the potential energy
and K(x) is the kinetic energy.

Therefore,
Conservation of Energy
This states that
The total energy of a system, E, can only change by amounts of
energy that are transferred to or from the system.
Work done can be considered as energy transfer, so we can write,

Emec is the chang

Conservation of Mechanical Energy

Equilibrium Points
Equilibrium Points: refer to points where, dU/dx=-F(x)=0.
Neutral Equilibrium: is when a particles total mechanical energy is
equal to its potential energy (i.e., kinetic energy equals zero). If no
force acts on the particle, then dU/dx

Work Done by an External Force
Previously we have looked at the work done to/from an object.
We can extend this to a system of more than one object.
Work is the energy transferred to or from a system by means of an
