Equations Flashcards
1
Q
What equation do we use to find componants?
A
avx = a cos (Ø) and avy = a sin (Ø)
2
Q
What equation do we use to find the velocity of an object?
A
s = ut + 1/2at²
3
Q
What equation do we use to find force?
A
F = ma
4
Q
What equation do we use to find the refractive index?
A
n = sinØvi/sinØvr
5
Q
How do we find the critical angle?
A
Sin Øvc = n²/n¹
6
Q
How do we figure out voltage?
A
V = IR
Or voltage = current x resistance
7
Q
How do we figure out power? 3
A
P = V²/R or P = I²R or P = IV
8
Q
What is the equation for voltage?
A
V = W/Q or voltage = work done/charge
