Question

Q.1. An object moves from A to D along the red path as shown above.
a) Find the total distance covered by the object
b) Find the displacement of the object (1 unit of graph = 1 km)​

Answer 1

Answer:

Explanation:

Using the given scale (1km per division); the total distance d is given by

d = AB + BC + CD = 2 + 5 + 2 = 9 km

b) The final and initial and positions of the moving object are used to find the displacement. The distance from A (initial position) to D (final position) is equal to AD = 5 km.

The displacement is the vector AD whose magnitude if 5 km and its direction is to the east.

Answer 2

Answer:

distance travelled=AB+BC+CD=2+5+2=9km

displacement=AD=5km
