- Conservation of energy when u get stuck
- Take care of approximation errors, remember the alpha problem
- leave force direction when calculating work with integration to the dot product
IMORTANT: review the slide proofs
NOTE: in under damped oscillations the amplitude decays with the same ration every cycle

- When given two things of the same type, maybe it can be solved by getting the ratio between them
If critical damping specified in a then b is also critically damped

- Acceleration always has constant sign in the same half

-
only tangentienal acceleration is used in newtons law of moton because it is what does work
-
derivative of linear velocity gives tangential accelration

-
identical springs then k is equal



- Stable equilibrium is when U is min, Unstable equilibrium is when U is max
