PHYSICS FORMULAE FOR RELATIONSHIPS

TAKEN FROM THE SPECIFICATION AND MUST BE REVISED BECAUSE IT WILL NOT BE PROVIDED IN EXAM. SYMBOL FORMULA MAY BE SLIGHTLY ALTERED FOR CONVENIENCE.

NOTE: IF P IS ALLOCATED AS DENSITY IT RESPRESENTS SYMBOL FOR PASCALS.

?
the relationship between average speed, distance and time
average speed = distance / time taken or v = d / t
1 of 21
the relationship between force, mass and acceleration
force = mass x acceleration or F = m x a, acceleration = force/mass
2 of 21
for acceleration
acceleration = change in velocity / time taken or a = v - u / t
3 of 21
the relationship between momentum, mass and velocity
momentum = mass x velocity or momentum = m x v
4 of 21
the relationship between density, mass and volume
density = mass / volume or p = m / v
5 of 21
the relationship between force, distance and work
work done = force x distance moved or W = F x d
6 of 21
the relationship between mass, weight and gravitational field strenght
weight = mass x gravitational field strength or w = m x g
7 of 21
the energy relationships
energy transferred = work done, kinetic energy = 1/2 x mass x speed^2, gravitational potential energy = mass x g x height
8 of 21
X-axis and Y-axis
X-axis is horizontal and always plots the independent variable such as time and the y-axis is vertical and always plots the dependent variable such as distance/height
9 of 21
Gravitational potential energy
G.P.E = mass x gravitational field strength (10) x height
10 of 21
the relationship between mass, weight and gravitational field strenght
weight = mass x gravitational field strength or w = m x g
11 of 21
The relationship between an applied force, the area over which it acts and the resulting pressure
pressure = force / area or p = F / A
12 of 21
the relationship between the moment of a force and its distance from the pivot
moment = force x perpendicular distance from the pivot or moment of force = F x d
13 of 21
the relationship between charge, current, voltage resistance and electrical power
charge = current x time, voltage = current x resistance, electrical power = voltage x current
14 of 21
the relationship between speed, frequency and wavelength
wave speed + frequency x wavelength
15 of 21
the relationship between voltage, power and the turns ratio for a transformer
input (primary) voltage/ output (secondary) voltage = primary turns / secondary turns or Vp / Vs = Np / Ns note: N is small n, here is shown only for size proportion towards s
16 of 21
the relationship between the refractive index and critical angle
sin c = 1 / n
17 of 21
the relationship between refractive index, angle of incidence and angle of refraction
n = sin i / sin r
18 of 21
efficiency
efficiency = useful energy output / total energy output x 100
19 of 21
the relationship for pressure difference (due to liquid)
pressure difference = height x density x g or p = h x p x g
20 of 21
the relationship between the power put into a transformer and the power it produces
input power = output power for 100% efficiency Vp X Ip = Vs x Is
