formulae

• work done = force x distance
• (final velocity)2 - (initial velocity)2 = 2 x acceleration x distance
• braking distance = kinetic energy / brake force
• thinking distance = speed travelling x reaction time
• force x time = change in velocity x change in mass
• force = mass x velocity
• acceleration = change in velocity / time
• moment = force x perpendicular distance from pivot
• pressure = depth x density x GFS
• m = Fd
• f = k (spring constant) x extension
• work done = force x displacement
• ke = brake force x distance
• f = ma
