- 1Speedspeed = distance / time
v = Δs / Δt - 2Accelerationacceleration = change in velocity / time taken
a = Δv / Δt - 3First equation of motionfinal velocity = initial velocity + accelerationxtime
v = u + at - 4Second equation of motiondisplacement = ½ (initial velocity + final velocity) x time
s = ½ (u + v)t - 5Third equation of motiondisplacement = initial velocityxtime + ½ accelerationxtime^2
s = ut + ½ at^2 - 6Fourth equation of motiondisplacement = initial velocity (final velocity – initial velocity / acceleration) = ½ acceleration (final velocity – initial velocity / acceleration) squared
s = u(v – u / a) + ½ a(v – u / a)^2 - 7Fifth equation of motionfinal velocity squared = initial velocity squared + 2 accelerationxdisplacement
v2 = u2 + 2as - 8Weightweight = mass x gravitational field strength
W = M x g - 9JoulesJoules = newton x meter
J = N x m
→ 1J = 1Nm - 10Kinetic energyKinetic energy = 0.5 x mass x velocity or speed
KE = 0.5mv^2 - 11Terminal velocityTerminal velocity = square root (2 x mass x gravity)/(density x projected area x drag coefficient)
V = √(2mg)/(ρAC) - 12GravityForce = mass x acceleration
F = m x a - 13DensityMass/unit volume
ρ = m/vol
