Document Summary

One of three formulas pick the one with only 1 missing variable. Determines distance travelled during particular time of flight. If ball thrown straight up = no horizontal distance travelled. Greatest distance covered when there is a compromise between time of flight and distance covered during that time. Eg. long jump beyond 20deg take off > horizontal velocity is decreased. Greater speed of release = greater horizontal distance. Alters compromise between velocity and time of flight. Rectilinear motion all parts of the object have the same speed. Amount of movement measured through the centre of mass. Eg. curvilinear motion all parts with same speed but with curved path. Angular motion different parts of the body have different speeds. Centre of mass may remain at 0 while extremities have higher velocity. Combination consists of both translation and rotation. Centre of mass used to measure translation. Use angles to measure rotation (eg. starting and finishing position)
