Question

what is the difference between distance and displacement in which case both are equal​

Answer 1

Key Differences Between Distance and Displacement

The following points explain the differences between distance and displacement:

The amount of space between two points, measured along the actual path, which connects the two points, is called distance. The amount of space between  two points, measured along the minimum path which connects them, is called displacement.

Distance is nothing but the length of the total route travelled by the object during motion. On the other hand, displacement is the least distance between starting and finishing point.

Distance gives the complete information of the path followed by the body. As against this, displacement does not give the complete information of the path travelled by the object.

Displacement decreases with time, whereas distance does not decrease with time.

The value of displacement can be positive, negative or even zero, but the value of the distance is always positive.

Distance is a scalar measure, which takes into account the magnitude only, i.e. we need to specify only the numerical value. Unlike displacement which is a vector measure and takes into account both magnitude and direction.

Distance covered is not the unique path, but the displacement between two locations, is the unique path.

While distance is represented by ‘d’, displacement is labelled as ‘s’.

Distance can be calculated by multiplying speed and time. On the contrary, the displacement can be calculated by multiplying velocity and time

Answer 2

(1)the distance is defined as the actual path travelled by the body means how much metre or kilometre travelled by body(2) it cannot be zero...

(1)Displacement is defined as the started and ending point of the body (2) It can be zero whereas the body start moving from point and then again come to that point then it can be zero
