Answer 1

Answer:

DISPLACEMENT

Displacement is the shortest distance from your initial position to your final position. Therefore, displacement is a measurement of distance and not an "end-point.

ZERO DISPLACEMENT

The object instead of moving through a distance can have zero displacement. Example: If an object travels from point A and reaches to the same point A, then its displacement is zero.

Answer 2

$\huge{\boxed{\boxed{\sf{\red{Required \: Answer}}}}}$

Displacement:

- The shortest or minimum possible distance of any object between its final and initial point is known as displacement.

- Displacement = Final position - Initial position

- Displacement is a vector quantity.

- Displacement can be positive, negative or zero.

- Let us take an example:

If an object is moving on a square track as shown in the figure then find the displacement of object.

Solution: Here the smallest path is making a right angled triangle between the square track.

Using Pythagoras theorem:

$\implies\sf{{H^{2} = P^{2} + B^{2}}$

$\implies\sf {{H^{2} = 8^{2} + 6^{2}}$

$\implies\sf{ {H^{2} = 64+36}$

$\implies\sf{ {H^{2} = 100}$

$\implies\sf {H} = \sqrt{100}$

$\implies\sf {H} = 10m$

So, the displacement is 10m.

Zero Displacement:

- The shortest or minimum possible distance of any object between its final and initial position is 0 then the displacement is zero displacement.

-Let us take an example:

There is a square path and a person travels the square path of 2m each side in 10sec each. What is the displacement after 40 sec?

Solution:

$\implies \sf { Δx = x1 - x2 }$

$\implies \sf { Δx = 0-0 }$

$\implies \sf { Δx = 0}$
