Term

Definition
break into components x and y add all x and ys then magnitude is = the square root of (xtotal^2 + ytotal^2) 


Term
finding theta of a vector 

Definition


Term

Definition
must multiply the x and y component of vector subtracted by 1 then same as adding 


Term

Definition
ratio of displacement/ ∆time
average velocity=∆x/∆t 


Term

Definition
at a single instant
v=lim ∆x/∆t as ∆t approaches 0 


Term

Definition
average speed=distance/time
s=d/∆t (scalar) 


Term

Definition
the magnitude of the instantaneous velocity vector (scalar) 


Term

Definition
is the change in instantaneous velocity over time
ā=∆v/∆t 


Term
instantaneous acceleration 

Definition
the acceleration at a specific point
a=lim ∆v/∆t as t approaches 0 


Term

Definition
v=v0+at x=v0t+(at^2)/2 v^2=v0^2+2ax average velocity=(v0+v)/2 x=(average velocity)t=((v0+v)/2)t
