Step 1: Distance and displacement

The distance is the whole length of the body's journey. The meter is the unit of measurement. It's a number that represents a scalar value.

The shortest distance between the beginning and finishing points is defined as displacement. It's a quantity that's been given a vector. The length is given in meters.

The distance and displacement will be the same only if the voyage is in a straight line.

Step 2: For particle D distance and displacement

Figure: Path of particle D

a. The distance travelled by the particle D is :

First, it goes from $x = 9 m to x = 3 m$ . The total distance covered is $6 m$ . Then the body comes back till $5 m$ , so it covers more distance. Now the total distance will be $6+ 2 = 8 m$ .

Thus, the distance covered by particle D is $8 m$ .

b. The magnitude of the displacement, in this case, will not be the same as the distance as it is not a straight path.

Displacement of the particle D = Final position – Initial Position

$\begin{array}{l} = 5 m - 9 m \\ = - 4 m \end{array}$

Thus, the magnitude will be 4 m.

c. The direction of the displacement would be $- 4 m$ as the body is moving in the negative x-direction.
