Physics Equations

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 V₀ 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_i²+2a(x-x₀)
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
