Question

q.2. a dog moves from point a to point b to point c, then back to point b along the line shown in the figure below. what is the dog’s distance and displacement?

Explanation:

Step1: Calculate distance

Distance is total path length. From A(0 m) to B(6 m) is 6 m, from B to C(11 m) is 11 - 6=5 m, from C back to B is 5 m. So distance $d=6 + 5+5=16$ m.

Step2: Calculate displacement

Displacement is straight - line distance from initial to final point. Initial point is A and final point is B. So displacement $s = 6-0 = 6$ m.

Answer:

Distance: 16 m, Displacement: 6 m
