
Batman is trying to catch
a woman that fell off a
building. Her velocity is
30m/s. Batman only has
1/3 second to catch the
woman before she hits the
ground. The woman
weighs 75Kg. Batman
does a one handed
catch. What is the force
exerted on his arm.

(hint. Solve for average
acceleration. Then solve
for force.)

What is Mechanical Energy?
Energy due to a
object’s motion (kinetic)
or position (potential).
o
The bowling ball has
mechanical energy.
When the ball strikes
the pins, mechanical
energy is transferred to
the pins!
Examples:
Examples of Mechanical Energy
Thermal Energy
o
The total energy of the
particles in an object.
o Heat energy
A hot object is one whose atoms and
molecules are excited and show rapid
movement.
A cooler object's molecules and atoms will
show less movement.
Examples:
Chemical Energy
o
Potential energy stored
in chemical bonds that
hold chemical
compounds together.
The chemical bonds in
a matchstick store
energy that is
transformed into
thermal energy when
the match is struck.
Examples:
Examples of Chemical Energy
Electrical Energy
The energy of
moving electric
charges.
o Easily transported
through power lines
and converted into
other forms of energy
Examples:
Electromagnetic Energy
The energy of light and
other forms of
radiation. (waves)
Examples:
Nuclear Energy
The potential
energy stored in
the nucleus of the
atom.

Fusion – is the joining
together of atoms,
(sun)

Fission – is the splitting of
an atom. (nuke,
nuclear plants)
