Today’s Topics The previous lecture covered measurement, units, accuracy, significant figures, estimation. Today we’ll focus on motion along a straight line: distance and displacement, average and instantaneous velocity and acceleration, the importance of sign . We’ll discuss the important constant acceleration formulas .

Kinematics: Describing Motion Kinematics describes quantitatively how a body moves through space. We’ll begin by treating the body as rigid and non-rotating, so we can fully describe the motion by following its center. Dynamics accounts for the observed motion in terms of forces, etc. We’ll get to that later.

Measuring Motion: a Frame of Reference Frame of reference: To measure motion , we must first measure position . We measure position relative to some fixed point O , called the origin . We give the ball’s location as ( x , y , z ) : we reach it from O by moving x meters along the x -axis, followed by y parallel to the y -axis and finally z parallel to the z -axis. The frame can be envisioned as three meter sticks at right angles to each other, like the beginning of the frame of a structure. O x y z ( x, y, z )
