Document Summary
Free body diagrams are pictorial representation that represent left side of newtons 2nd law. Need to understand common forces in human movement. Identify possible mechanical action forces that happen between contact of systems: rope like structures. Pulling on rope (direction of force will be applied on to that force. Pulling on force creates force in 1 direction (tension: contact with rough surface. Action: take body of interest and replace eternal contacts with the surface which always pushes against the body. Forces acting the same are known as centre of pressure: contact with smooth surface. Skater: assume frictionally component is 0: free rotation around an axle (pin joint free to move) Action: axle replaced by force in any direction, pushing or pulling acting at centre of rotation: constrained rotation around an axle. The vertical and horizontal force comes at it and movement is also occurring at same time.
