Physics Flashcards
Vector
Has a magnitud and direction
Includes:
- displacement (s)
-velocity (v)
Scalar
Only has a magnitud/size
Includes:
-distance
-speed or rate
Velocity formula
v=Displacement/change in time
Must specify direction
Rate/ speed formula
r= distance/ change in time
Aceleration formula
a= change in velocity/ time
Displacement formula
s= 1/2(a)(t)^2+v0t
Kinematic equation 1
d= 1/2(vi+vf)t
delta(x)-desplacement
t- time
vi- initial velocity
vf- final velocity
Kinematic equation 2
vf=vi + at
a- acceleration
t- time
vi- initial velocity
vf- final velocity
Kinematic equation 3
delta(x)= vi*t + 1/2at^2
a-acceleration
delta(x)- desplacement
t-time
vi- initial velocity
Kinematic equation 4
vf^2= vi^2 + 2a*delta(x)
a-acceleration
delta(x)- desplacement
vf= final velocity
vi- initial velocity
Free fall
t= sqrt2y/g
Newtons 1st law
Fnet=0
Fnet- net force on an object
Newtons 2nd law
Fnet=ma
Fnet- net force on an object
m-mass
a-acceleration
