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
• If appropriate, draw a diagram
• define important variables (S.I. units).
• State what principle you’re going to use.
• 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 &amp; circular.
• Relativity
• Conservation Laws and their uses:
-Momentum
-Energy
• Force and Newton’s Laws of Motion.
• Rotations and Rigid bodies
ALL FORMULAS COME FROM THE CHEAT SHEET!
• Calculus in action: Kinematics 3D
• Galilean Relativity (absolute t):
• Special Relativity (absolute c):
• Conservation Laws and their uses:
momentum:
Kinetic energy:
• In special relativity:
• Interactions and Forces.
(impulse)
(Force)
work:
(potential energy)
(power)
• Some Forces:
Static Friction
Kinetic Friction
Spring force
Gravitational Potential Energy:
(near surface)
Spring Potential Energy:
• Rotational Kinematics
• Rigid bodies: centers of mass, moments of inertia
•Linear-to-Rotational Dynamics Rosetta Stone
Velocity:
Momentum:
(sometimes)
Force:
Newton’s 2nd Law:
