Physics Mock equations Flashcards
1
Q
force equation
A
F=MA
2
Q
acceleration equation
A
acceleration = change in velocity / time taken
3
Q
density
A
density (ρ) = mass / volume
4
Q
work done
A
work done = force x distance moved
5
Q
kinetic energy
A
ke = 1/2 x mass x speed^2
6
Q
gravitational potential energy
A
gpe = mass x g x height
7
Q
energy transferred
A
energy transferred = work done (= force x distance mvoed)
8
Q
pressure
A
pressure = force / area
9
Q
moments
A
moment = force x perpendicular distance from pivot
10
Q
charge
A
charge = current x time Q=IT
11
Q
voltage
A
voltage = current x resistance V=IR
12
Q
wave speed
A
wave speed = frequency x wavelength V = Fλ
13
Q
in transformer equation
A
input voltage / output voltage = primary turns / secondary turns
14
Q
refractive index
A
n = sin i / sin r
15
Q
critical angle
A
sin c = 1 / n (sin^-1 x 1/n = c)
