ap physics c mechanics unit 1: kinematics

based on a bunch of videos i watched on youtube

motion

defined as the change of an objects position with time

position

where an object is placed (x-axis)

four basic types of motion

linear, circular, projectile, rotational

motion diagram

show project position at different times

help view speed in each frame

reference frame

position, distance, or speed using coodinate axis

distance

add all legs (absolute value)

displacement

final - inital position (can be - based on direction)

average seped

total distance/time took to travel

velocity

magnitude and direction of object moving

magnitude

numerical value

formula for velocity

average velocity

uses displacement instead of distance

→ right (+) and left (-)

instantaneous velocity

average velocity over short time interval

derivative

object slows down what is velocity and acceleration

opposite directions

speeding up, what is velocity and acceleration

same direction

instantaneous acceleration

second derivative

limiting value of aevrage acceleration and as tim approaches 0

CAKE

constant acceleration kinematic equation

projectile motion shape

parabola
