Describe Motion Verbally with Distance and Displacement

Introduction to Kinematics Reading #1 Scalars and Vectors Reading #2 Distance versus Displacement Reading #3 Vectors OR Scalars?Most of the quantities used to describe motion can be categorized as either vectors or scalars.A Vector is a quantity that uses both magnitude and direction.A Scalar is a quantity that uses ONLY magnitude.Categorize the following quantities by sorting them as either vectors or scalars. Vectors displacement velocity Scalars acceleration speed distance A quantity that ignores directionis considered... scalar vector A quantity that uses direction is considered... scalar vector Distance vs. Displacement As an object moves, its location changes. There are two quantities that are used to describe the changing location.One quantity - distance - accumulates the amount of total change of location over the course of a motion. Distance is the amount of ground that is covered.The second quantity - displacement - only concerns itself with the initial and final position of the object. Displacement is the overall change in position of the object from start to finish and does not concern itself with the accumulation of distance traveled during the path from start to finish. True or False: An object can be moving for 10 seconds and still have zero displacement. true false If the above statement is true, describe an example of that kind of motion.If the statement is false, explain why. Suppose that you run along three different paths from location A to location B. Which path(s) show that your distance traveled is different than your displacement? Distance and Displacement while running What distance did you travel? What was the displacement of the entire trip? Graphing Motion Observe the diagram below. A person starts at A, walks along the bold path and finishes at B. Each square is 1 km along its edge. Use the diagram in answering the next two questions. How many km does this person walk? 3 km 13 km 31 km What is this person's displacement in km? 0 km 3 km 31 km Cross Country Skiing What is the distance traveled by the skier during the three minutes of recreation? What is the net displacement of the skier during the three minutes of recreation? What is the displacement during the second minute (from 1 min. to 2 min.)? What is the displacement during the third minute (from 2 min. to 3 min.)?
