Motion (along with momentum and energy) is one of the building blocks to our treatment of Einstein's Special Theory of Relativity.

• You will understand how velocity relates to distance and time.
• You'll become experienced with two of our three “motion diagrams”: Space-Diagrams and Spacetime Diagrams.
• You'll be able to calculate velocities from $v=\frac{\Delta x}{\Delta t};$ accelerations from $a=\frac{\Delta v}{\Delta t};$ and, by limiting ourselves to constant acceleration, you'll learn that the distance traveled under that condition is $x = \frac{1}{2}at^2$.
• Finally, you'll appreciate that the “falling” near the earth is due to a constant acceleration which was found by Galileo Galilei, but not understood until Isaac Newton.

Momentum! is one of Newton's very important “discoveries” and we'll use it repeatedly. It's $p=mv$…where $m$ is mass (another Newton invention) and $v$ is velocity.

• You'll learn how momentum is related to force as $F\Delta t = \Delta p$
• You'll play with Newton's 3 laws of motion, but we'll not dwell on details of force problems like you would in a comprehensive physics course. Again, we're aiming at Relativity!
• We'll spend most of our time on linear momentum ideas, but we will need to cover circular motion in order to follow Newton's Universal Law of Gravitation.
• You'll learn how to play golf.

Much of our interest in particle physics comes from analyzing collisions of protons with protons (or antiprotons!), electrons with antielectrons, or neutrinos with protons, and so on. We'll concentrate on just a few configurations of one thing colliding with one thing. Buried in this discussion is the important concept of momentum conservation.

• You'll learn how collisions “conserve” momentum…and about the crucial idea of “conservation laws.” Nature loves conservation laws.
• You'll see neutrinos.
• You'll learn to skate and how to become a neutron star.

Electricity and Magnetism were formalized in the middle of the 19th century after inventing the very useful concept of the “field.”
