A2 - Kinematics in 1D

what are the three most important variables in kinematics?

position, velocity, and acceleration

speed is ____, while velocity is ____

scalar, vector

how is displacement different from distance?

displacement = space from relative point, distance = how much travelled

what are the two most important types of instant velocity?

initial velocity and final velocity

what is acceleration?

change in velocity and/or direction

if acceleration is uniform, what is the formula for it (in terms of time, initial velocity, and final velocity)?

(vf - vi)/t

when you are going down/left and slower, then acceleration is…

positive

when you are going down/left faster, acceleration is…

negative

when you are going right and up and faster, acceleration is…

positive

when you are going right/up and slower, acceleration is…

negative

what are the five fundamental variables of kinematics?

initial velocity, final velocity, displacement, time, and acceleration

what is the most basic kinematic equation that sets the basis for the other two basic ones?

vf = vi + at

what is the most important variable in a kinematic equation/problem?

initial velocity
