Minute Minder #5 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.)

TYPES OF ENERGY

• Mechanical• Thermal• Chemical• Electrical• Electromagnetic• Nuclear

What is Mechanical Energy?o Energy due to a object’s motion

(kinetic) or position (potential).

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)
