Three units to remember?
MKS= meters/ kg/ sec
CGS= cm/g/ sec
ENG= feet/ slugs/ sec
X =
[L]
V=
[L/T]
T=
[T]
Convert V to X:
[L] = [L/T] [T]
x=vt
What does V
_{0}
mean?
has velocity of the holder initially
If the holder is moving, the initial velocity is that of the holder
Explain gravity.
a force downward. And since this is opposite of our coordinate system, it is usually negative
Equation used for determining how fast something is?
V= V0+at
Interested in speed? Use:
V^2=V
_{i}
^{2}
+2a(x-x
_{0}
)
To find position, what equation is used?
x= x(initial)+ v(initial)t+ (1/2)at^2
To find velocity under a constant acceleration?
V= at+ v(initial)
For velocity in terms of position?
V^2=Vi2+2a(x-x0)
Position as a function of Time and Velocity
x= x0+(1/2)(v0+v)t
