Answer 2

Answer:

Change in position in a particular direction is Displacement.

Explanation:

• Displacement: If an object change its position in a particular direction then the shortest difference between the final point and initial point is called displacement.
• Displacement = Final point - Initial point (along straight line).
• If there is no change in direction or the object is moving along a straight line then distance = displacement.
• Displacement is a vector quantity because it depends on direction.
• Example - Suppose a person is running along a circular ground of radium 4m. After half covering the circular path its displacement can be calculated as = 2 × radius of the circle

                                    = 2 × 4 m = 8m.

      Where distance = $\frac{1}{2}$ × perimeter of the circle = π × 4 = 12.6 m

• Distance can be greater the displacement and displacement can be zero when the object has covered some distance.
