Equations

• W = mg
• Weight = mass x gravitational field strength
• W = Fs
• Work done = force x distance (moved along the line of action of the force)
• F = ke
• Force = spring constant x extension
• Moment of a force = force x distance (perpendicular to the direction of the force)
• M = Fd
• Pressure = force normal to a surface/ area of surface
• Distance travelled = speed x time
• s = vt
• Acceleration = change in velocity/ time taken
• acceleration = (final velocity - initial velocity)/ time taken
• resultant force = mass x acceleration
• momentum = mass x velocity
• pressure = height of column x density x gravitational field strength
• (final velocity)^2 - (initial velocity)^2 = 2 x acceleration x distance
• Force = change in momentum/ time taken
