what is the formula for speed?

speed = distance / time

what is the formula for acceleration?

acceleration = change in velocity / time taken

a in m/s²

Δv in m/s

t in s

what equation links final speed, initial speed, acceleration and distance?

v² = u² + 2as

(final speed)² = (initial speed)² + (2 × acceleration × distance moved)

s in m

u in m/s

v in m/s

a in m/s²

what equation links force, mass, and acceleration?

F = ma

F in N

m in kg

a in m/s²

what is the equation linking weight, mass, and gravitational field strength?

W = mg

W in N

m in kg

g in N/kg

what is the formula for stopping distance?

stopping distance = thinking distance + braking distance

what is the equation for momentum?

p = mv

p in kg m/s

m in kg

v in m/s

what is the equation for change in momentum?

Δp = mv - mu

Δp in kg m/s

m in kg

v in m/s

u in m/s

what is the equation linking force and change in momentum?

F in N

m in kg

v in m/s

u in m/s

t in s

what is the equation for the size of a moment?

M = Fd

M in Nm

F in N

d in m
