So in general . . . a dot product is an accounting method that pops out a number which rates you how much two vectors agree with each other.

more examples of Work being the integral of force function with respect to distance.

Derivation of Work – Kinetic Energy Equation

Just for fun . . . here is the calculus version of the derivation of the Work-Kinetic Energy equation.

Ug = the gravitational potential energy of an object. It gives you an accounting of how much MECHANICAL energy that is POSSIBLE due to the position of the object.

zpl — Zero Potential Level (at that point gravity can do no more work.

Here are some examples of different types of potential energies.

Ahhhh . . . the baby UFT.

UFT is another name for the First Law of Thermodynamics.

W-K Theorem and UFT on the same screenshot. TOO MUCH AWESOMENESS!

The FULL UFT.

Next year . . .

The REAL UFT.

Pendulum. Pa Pa Pa Pa Ne Ne Ne Ne

UFT’s take on the pendulum.

An excellent screenshot. A good one for your notebook.

Simple Harmonic Motion

SHM example. Remember: omega = how fast the wheel spins or how fast the pendulum goes back and forth = 2Ï€ / Tp where Tp = the time it takes for one oscillation.

A VERY good screenshot for your notebook

The two conditions of a conservative force.

Pacman (Friction) eats all along the path and does NOT give back. Friction is NOT conserved. Friction causes damping. See the next pic.

Most classes didn’t have enough time to get into damping envelopes.

an excellent example of W-K theorem. Another good one for your notebook.

Using W-K to determine stopping distance.

Tesla -Westinghouse gave us a new equation for Power.

Use the units to help you come up with new formulas. It’s fun!!

OG&E is an ENERGY company, not a Power company. That’s why your bill is in terms of Kilowatt-Hours. Power x time = Energy

Using UFT to quickly solve a problem. With UFT and W-K we can say goodbye to the beloved Orange and Blue equations.

A horrible pic of the awesome Modern Dance presentation.

Rocketry Party. Launch is set for the afternoon of March 21st.

Rocketry Party.

16th annual Physics Picnic was a big success!

These people got VERY serious about their volleyball!
