Worked examples

Newton’s laws and forces

One sheet for each type of problem, with several worked examples of increasing difficulty: first the computation, then the explanation in words. Each sheet starts with links to the theory it uses.

• 1Bodies subject to constant forces
• 2Bodies in equilibrium hanging from strings
• 3Inclined planes
• 4Problems with sliding friction on horizontal surfaces
• 5Bodies connected by strings and pulleys
• 6Springs and elastic force
• 7Dynamics of circular motion
