General Principles Problem Solving, not formula-remembering. Read the exam instructions and know what’s on the cheat-sheet. Mental cog-wheels: CAREFULLY READ the entire exam at start. Choose which battles to fight and when to fight them. Time discipline, when studying and when writing. If you are in a hole, stop digging.
How to Approach a Problem Read the question. Don’t answer what isn’t asked! If appropriate, draw a diagram define important variables (S.I. units). State what principle you’re going to use. Don’t jump too many steps; put in numbers at end. Clearly state final answer (a box would be nice). Checks: -does number make sense? -do dimensions match?
Topics: Calculus in action: Kinematics in 1, 2 and 3D & circular. Relativity Conservation Laws and their uses: -Momentum -Energy Force and Newton’s Laws of Motion. Rotations and Rigid bodies
Calculus in action: Kinematics 3D ALL FORMULAS COME FROM THE CHEAT SHEET!
Galilean Relativity (absolute t ): Special Relativity (absolute c ):
Conservation Laws and their uses: Kinetic energy: momentum: In special relativity:
Interactions and Forces. work: (impulse) (Force) (potential energy) (power)
Kinetic Friction Static Friction Spring force Some Forces: Gravitational Potential Energy: Spring Potential Energy: (near surface)
