Document Summary
Object moving at constant speed in a straight line (ie. moving constant velocity) Paddling a canoe moving north straight across a lake at a constant speed 2. 0m/s. Draw graph of displacement of the canoe as a function of time. = 0m at time 0s north is positive. Ie 2 you find a mother bear and cubs waiting at the shore you turn around and paddle @ Since north is defined as positive, velocity is in the south direction. Displacement vs time a straight line with the slope equal to the (constant) velocity. Velocity vs time graph a flat line (constant velocity) For any velocity vs time graph the area under the curve gives the objects displacement over time that interval. Plot the velocity of the canoeist vs time and determine: the displacement of the canoeist in the first 750 seconds, the displacement of the canoeist form 750s to 1125 seconds, total displacement = 0m.
