Three friends Ram, Mohan, and Roy have to reach point B from point A. The
path taken by them is shown in the figure. The figure is showing a circular
path having the radius of 5m.

d.
Distinguish between distance and displacement.
What are the Mathematical values of the distances and displacements
for all the three friends?
If all of them travel at the same speed, who will reach first at point B
and why?
Define circular motion for a body.

Answer :

Answer:

Explanation:Distance is the total length of the path traveled by an object, while displacement is the shortest distance between the initial and final positions of the object, along with the direction from start to end.

1. Mathematical values for distances and displacements for Ram, Mohan, and Roy:

- Ram:

- Distance = Circumference of the circle =

- Displacement = Diameter of the circle =  (since the shortest distance between two points on a circle is along its diameter)

- Mohan:

- Distance = Circumference of the circle =

- Displacement = Diameter of the circle =

- Roy:

- Distance = Circumference of the circle =

- Displacement = Diameter of the circle =

2. If all three friends travel at the same speed, the one who will reach point B first is the one who covers the shortest distance. In this case, since all of them have the same displacement of 10m, they will all reach point B at the same time.

3. Circular motion for a body is the movement of an object along a circular path where the object continuously changes its direction. The object moves in a circular trajectory around a fixed point or axis. In circular motion, the object maintains a constant radius from the center of the circle while moving.
