Name Distance and Displacement Write definitions for distance and displacement in the blanks below. How much ground an object has covered during its motion 1. Distance - 2. Displacement - How far out of place the object is (object's overall change in position) *You may leave direction out of your answers for displacement for the rest of the worksheet. 3. The typical baseball diamond is a square 90 ft long on each side. Suppose a player hits a homerun and makes one complete trip from home plate, around the bases, and back to home plate. Complete the table by finding the player's distance and displacement as he rounds the bases. Include the proper units. All angles are right angles. (Hint: You may need Pythagorean’s theorem for 2nd base.) distance displacement at home plate at 1st base at 2nd base 0 ft 90 ft 180 ft 0 ft 90 ft 90sqrt2 ft (127.28) 90 ft 4. (over) 0 ft 0 meters 800 meters displacement = A. less than C. equal to E. greater than 360 ft The runner completes exactly 2 laps around a 400 m track. distance = For any object in motion, distance is always back at home 400 meters displacement = 6. 270 ft A runner at a track meet completes exactly one lap around a 400 m track. distance = 5. at 3rd base D 0 meters displacement. B. less than or equal to D. greater than or equal to 7. A bug walks exactly halfway around the edge of a circular cupcake with a diameter of 5 cm. distance = 7.855 cm displacement = 8. 5 cm A swimmer swims a half lap, moving from the left end to the right end of a pool that is 50 meters long. distance = 50 meters displacement = 50 meters 9. A swimmer swims an entire lap, moving from the left end to the right end and back again to the left end in a pool that is 50 meters long. distance = 100 meters displacement = 0 meters 10. For a typical day in your life, from the time you get out of bed in the morning to the time you climb back into your bed at night, estimate the following: distance = 6 miles displacement = 0 miles 11. Think of the total distance you have covered in your lifetime. Is it possible for you to move in some direction to reduce this distance to zero? No 12. If so, where would you go? If not, why not? You can't reduce distance to zero because distance is always positive. I can't go negative distance to reduce distance. 13. Is it possible for you to make your lifetime displacement equal to zero? Yes 14. If so, where would you go? If not, why not? Yes, I would just go to the hospital room and bed that I was born in.
