Question

An object moves from point A to point B, then back to point A along the line shown in the figure belowOkmTim2km3km4lom5km6km7km8km9km10km11 kmWhat is the objects distance?What is the objects displacemt

Answer 1

The object's distance = 10km

Displacement of the object = 0

From the line:

The distance from A to B = 5km

The distance from B to A = 5km

The object's distance = distance A to B + distance B to A

The object's distance = 5km + 5km

The object's distance = 10km

The displacement is the change in position of an object.

Displacement = final distance - initial distance

final distance = 5km

initial distance = 5km

Displacement = 5km - 5km

Displacement of the object = 0
