- 1Give the equation for accelerationacceleration = change in velocity ÷ time
a = (v-u) ÷ t - 2Make mass the subject of the formula: f = m x am = f ÷ a
mass = force ÷ acceleration - 3Give an equation for powerpower = work done ÷time taken
power = energy transferred = time taken - 4Give an equation for electrical powerelectrical power = current x potential difference
electrical difference = current squared x resistance - 5Give an equation for wavespeedwave speed = frequency x wavelength
wave speed = distance ÷ time - 6energy transferred = ?energy transferred = charge moved x potential difference
E = Q x V - 7force exerted on a spring = ?force exerted on a spring = spring constant x extension
F = k x x - 8Rearrange: KE = 1/2 x m x v2 to make v the subject of the formulav squared = 2(KE) ÷ m
or
v = square root of 2 (KE) ÷ m - 9Rearrange KE = 1/2 x m x v2 to make m the subject of the formulam = 2(KE) ÷ v squared
- 10density = ?density = mass ÷ volume
p = m ÷ v - 11What is the written formula for P = E ÷ t?Power = (energy transferred or work done) ÷ time taken
- 12Charge = ?Charge = current x time
Q = I x t - 13Change in GPE = ? ( ΔGPE)Change in GPE = mass x gravitational field strength x change in vertical height
ΔGPE = m x g x Δh - 14momentum = ? p = ?momentum = mass x velocity
p = m x v - 15The word equation for V = I x R?potential difference = current x resistance
- 16What is the word equation for E = F x d?Work done = force x distance moved in direction of the force
- 17Pressure = ?Pressure = force normal to surface ÷ area of that surface
P = F ÷ A - 18Moment of a force = ?Moment of a force = force x distance normal to the direction of the force
