Document Summary
Read section 1. 1-1. 4 on quiz #1. Read sections 2. 3, 2. 4 for next lectures. Scalar a quantity that has magnitude but no direction. Vector a quantity that has both magnitude and direction. In physics, the arithmetic is different when dealing with vectors compared with scalars. Displacement indicates the change in position from the starting point the final point. From the greek word for motion (kinema) Throw a ball straight up and it falls back down. 0m when ball falls back to starting point) Average velocity defined as the rate of change in displacement scalar or. Displacement vs time graph is a straight line. For ant displacement vs time graph, the slope gives the objects velocity. In thee case of uniform motion, the slope is the same at all points in time since the object is travelling at a constant velocity. Graphical representation can also be extended to plotting an objects velocity vs. time.
