As an effort to save time and work, you will find a template that has space for you to type in your response to the laboratory questions. Introduction One of the most fundamental concepts in the physical sciences is the description of motion, or what is called kinematics. The key concepts in the description of motion are speed, velocity, and acceleration. These concepts can be expressed as mathematical functions or graphically. It is the ratio of distance to time.
Velocity is a speed with an associated direction .
If we consider motion along a number line, we can specify positive and negative velocities as meaning motion in a positive or negative direction. The slope in a distance vs. time graph gives the sign of the velocity. Note that this is the ratio of velocity to time and is represented as the slope of a velocity time graph. I Describing Motion 1. At the laboratory table are a series of toys.
