AP physics TCA 1 & 2 must remembers

slope of velocity vs time graph is what

acceleration

area under the velocity vs time graphs is

displacement

x velocity is what in projectiles

constant

y velocity for projectiles is what

-9.8

down the slope is what

mg sin theta

into the slope is what

mg cos theta

what should you always start out with on dynamics problems

F = ma

N2L is what

F = ma

N1L is what

an object at rest remains at rest until acted on by an external force

N3L is what

every action/force has its opposite but equal reaction

what should you always start off with when doing energy problems

Ef = Ei

When dropping an object off a ledge or dropping an object in general, what factors are zero

velocity initial and kinetic energy initial

the force pointing towards the center is what

positive

equation for center force

mv²/r

if a problem asks for time use

kinematics

if a problem asks for friction, acceleration, or force use

dynamics

if a problem asks for speed or height and no time is given use

energy (Ef = Ei)

if the problem is talking about a radius or circular path use

circular motion (net force points to center)

when velocity and acceleration have opposite signs (+ velocity, - acceleration), what happens

they oppose each other, causing the object to slow down

velocity vs time graph under the curve is what

displacement

acceleration vs time graph under the curve is what

change in velocity

force vs displacement graph under the curve is what

work done or change in kinetic energy
