Explain the concept of relative displacement.

Relative displacement is the change in position of an object with respect to another object.

Relative displacement is a vector quantity that describes the change in position of an object with respect to another object. It is calculated by subtracting the initial position vector of the second object from the final position vector of the first object.

For example, if object A moves from position (2,3) to position (5,7) and object B moves from position (1,1) to position (4,5), the relative displacement of object A with respect to object B is:

(5,7) - (1,1) = (4,6)

This means that object A has moved 4 units to the right and 6 units upwards with respect to object B.

Relative displacement can also be negative if the two objects move in opposite directions. For example, if object A moves from position (2,3) to position (5,7) and object B moves from position (6,5) to position (3,1), the relative displacement of object A with respect to object B is:

(5,7) - (6,5) = (-1,2)

This means that object A has moved 1 unit to the left and 2 units upwards with respect to object B.

Relative displacement is an important concept in physics and engineering, as it is used to describe the motion of objects in relation to each other.
