On an axis in which moving from right to left is positive, what is the displacement and distance of a student who walks 32 m to the right and then 17 m to the left? Displacement is -15 m and distance is -49 m .
1 lut 2015 · FORM 4: 2.1 ANALYSING LINEAR MOTION. Distance is the total path length travelled from one location to another. Displacement is the distance between two locations measured along the shortest path connecting them, in a specified direction. Speed is the rate of change of distance. Velocity is the rate of change of displacement.

practice problem 1. I went for a walk one day. I walked north 6.0 km at 6.0 km/h and then west 10 km at 5.0 km/hr. (This problem is deceptively easy, so be careful. Begin each part by reviewing the appropriate physical definition.) Determine… the total distance of the entire trip. the total displacement of the entire trip.
Given: Use the facts that the distance d to the Moon is about 240,000 miles, and the typical person can walk at a speed, v, of about 3 miles/hour (without breaks). Concept(s): Use the concept that v = d/t → t = d/v.
The experiment shows that the times to cover successive 25 cm distances decrease. It also demonstrates difficulties in measuring short time intervals of less than a second, as well as measuring continuous time.
