State the relationship between average speed, distance moved and time taken
average = distance moved / time taken
State the relationship between acceleration, change in velocity and time taken
acceleration = change in velocity / time taken or a = (v-u) / t
State the relationship between final speed, initial speed, acceleration and distance moved
(final speed)² = (initial speed)² + (2 x acceleration x distance moved) or v² = u² + (2 x a x s)
State the relationship between force, mass and acceleration
Force = mass x acceleration or F = ma
State the relationship between weight, mass and g.
weight = mass x g or W = m x g
State the relationship between momentum, mass and velocity.
momentum = mass x velocity or p = m x v
State the relationship between force, change in momentum and time taken
force = change in momentum / time taken or F = (mv-mu)/t
State the relationship between moment, force and perpendicular distance from pivot.
moment = force x perpendicular distance from pivot
State the relationship between power, current and voltage.
power = current x voltage or P = I x V
State the relationship between energy transferred, current, voltage and time
energy transferred = current x voltage x time or E = I x V x t
State the relationship between voltage, current and resistance
voltage = current x resistance or V = I X R
State the relationship between charge, current and time
Charge = current x time or Q = I x t
State the relationship between voltage , energy and charge.
voltage = energy / charge or V = E/Q
State the relationship between wave speed, frequency and wavelength
wave speed = frequency x wavelength or v = f x λ
State the relationship between frequency and time period.
frequency = 1 / time period or f = 1/T
State the relationship between the refractive index and the angles of incidence and refraction.
n = sin i / sin r
State the relationship between the critical angle and the refractive index.
sin c = 1 / n
State the equation for efficiency.
efficiency = (useful energy output / total energy input) x 100%
State the relationship between work done, force and distance moved.
work done = force x distance moved or W = F x d
State the relationship between gravitational potential energy, mass, gravitational field strength and height.
gravitational potential energy = mass x gravitational field strength x height. or GPE = mgh
State the relationship for kinetic energy, mass and speed
kinetic energy = 1/2 x mass x speed² or KE = 1/2 x m x v²
State the relationship between power, work done and time taken
Power = work done / time taken or P = W/t
State the relationship between density, mass and volume.
density = mass / volume or ρ = E/A
State the relationship between pressure difference, height, density and gravitational field strength
pressure difference = height x density x gravitational field strength or p = h x ρ x g
