![]() ![]() ![]() What is your (a) distance traveled, and (b) displacement?Ĭhapter 2 One-Dimensional Kinematics Q.5CQĪfter a tennis match the players dash to the net to congratulate one another. In Figure 2-20, you walk from the park to your friend’s house, then back to your house. The distance traveled by the astronaut is equal to 2◊R, where R is the radius of the orbit.Ĭhapter 2 One-Dimensional Kinematics Q.4P In this situation, displacement is zero because the initial and final positions are the same (displacement = final position – initial position). In one complete orbit, is the magnitude of the displacement the same as the distance traveled? Explain. If we drive in a straight line, our distance and displacement are equal.Īny deviation from a straight line results in a distance that is greater than the magnitude of the displacement.Ĭhapter 2 One-Dimensional Kinematics Q.3PĬhapter 2 One-Dimensional Kinematics Q.4CQĪrt astronaut orbits Earth in the space shuttle. If we drive in a complete circle, the distance covered by us is equal to the circumference of the circle, while our displacement is zero. The distance measures the actual path of an object that takes in its motion and displacement measures the overall distance from the initial and final position of the object.Ĭhapter 2 One-Dimensional Kinematics Q.2CQĭoes an odometer in a car measure distance or displacement? Explain.Īn odometer in a car measures distancel because it does not tell us the direction in which we are traveling.Ĭhapter 2 One-Dimensional Kinematics Q.2PĬhapter 2 One-Dimensional Kinematics Q.3CQĬan you drive your car in such a way that the distance it covers is (a) greater than, (b) equal to, or (c) less than the magnitude of its displacement? In each case, give an example if your answer is yes, explain why not if your answer is no. The displacement is a vector quantity which is defined as how far an object travelled from its initial position The distance is defined as a scalar quantity which is equal to how much ground that an object covered during its overall motion. Referring to Fig ure you walk from your home to the library, then to the park (a) What is the distance traveled? (b) What is your displacement? while the distance traveled by the dog is greate than the distance traveled by usĬhapter 2 One-Dimensional Kinematics Q.1P The displacement is the same for the dog and us. and so on When you arrive at the park, do you and your dog have the same displacement? Have you traveled the same distance? Explain. your dog takes many short side trips to chase squirrels, examine fire hydrants. You and your dog go for a walk to a nearby park On the way.
