moment (turning effect) of a force, also called torque and its cgs and SI units; common examples - door, steering wheel, bicycle pedal, etc.; clockwise and anti-clockwise moments
Write an expression for the change in momentum of a body of mass m moving with velocity v if v << c.
Describe a simple experiment to verify the principle of moments, if you are supplied with a metre rule, a fulcrum and two springs with slotted weights.
State the relationship between force, mass and acceleration. Draw graphs showing the relationship between Acceleration and force for a constant mass.
A uniform metre scale can be balanced at the 70.0 cm mark when a mark when a mass 0.05 kg is hung from the 94.0 cm mark
1) draw a diagram of the arrangement
2) Find the mass of the metre scale
