A" Read aloud POGIL: Velocity and Displacement Position, Distance and Displacement To answer the question "How do things move?", we often want to know where an object is located and how far it is from its initial location. For one dimensional motion, we define the following quantities for such descriptions: • position - identifies where the object is located relative to a reference point on a line, called the origin. If the object is to the right of the origin, the position is given as a positive distance from the origin. If the object is to the left of the origin, the position is given as a negative distance from the origin. A C -4 m -3 m -2 m -I m O Im 2 m 3 m 4 m For example: • point A is 2 m to the left of the origin and therefore has a position of x = -2m • point B is 1 m to the right of the origin; it has a position of x = +1 m • point C is 2.5 m to the right of the origin; it has a position of +2.5 m. • distance - how far an object traveled. This does not matter which way an object goes. If you take a tape measure and measure the path in which an object travels, then this measurement would be the distance. • displacement- the change in an object's position. It gives the distance between the initial and final positions of an object's motion AND the direction from the initial to final point. If the final position is to the right of the initial position, then the displacement is positive; if the final position is to the left of the initial position, then the displacement is negative. 1.

A Read aloud Draw 2. Use the position vs. time graph to answer the following questions. (a) What is the person's average speed from: i. O to 6 s? ii. 6 to 8 s? iii. 8 to 12 s? iv. O to 12 s? (b) What is the person's average velocity from: i. O to 6 s? ii. 6 to 8 s? iii. 8 to 12 s? iv. O to 12 s? (c) During what time interval(s) is the person at rest? (d) During what time interval(s) are the speeds/velocities constant? (e) During what time interval(s) does the person move in the positive direction? (f) During what time interval(s) does the person move in the negative direction? Making a Speed and Velocity vs time graph The information you read from a position vs time graph can be used to make a speed vs time graph and a velocity vs time graph. If the speed or velocity is constant, then the speed/velocity is the same value for that given period of time. Using the information from the position vs time graph, and the answers on this page, construct a speed vs time graph and a velocity vs time graph. Make sure you fill in the appropriate numbers (based on your calculations) on the y-axis.
