Summary: Physics_181_Equation_Sheet_for_Exams______
o Chapter 1: Conceptual, no equations
o Chapter 2: 1D Motion along the s-axis:
Average: vsavg= _s_ tasavg= _vs_ tR Instantaneous: vs = ds_dtas = dvs_dt *
* R
Position from velocity: sf = si+ tftivsdt Velocity from acceleration: v*
*f = vi+ tftiasdt
Rtf h (n+1)it*
*f n n+1 n+1o
A Useful derivative and integral: d_dt(ctn) = cnt(n-1) tictndt = c t___n+1=*
* _c_n+1tf - ti
(c and n are constants) ti
Constant Acceleration: sf = si+ vsi t + 1_2as t2 vsf= vsi+ as t v2sf= v2si*
*+ 2as s
. where: t = tf - ti s = sf - si
Free Fall: ay = -g (if +y is up); Inclined Plane: ax = g sin` (if +x is down*
* incline)
