Question

what is the distance travelled and displacement when a person starting from A and ends at A after travelling circular path of radius 7meter​

Answer 1

Given

• Radius of the circle = 7 m
• Initial point = A = Final Point

To Find

• Distance and the displacement

Solution

● Distance : Length of the total path covered by a body

● Displacement. : The shortest path between the initial and the final point

✭ Displacement of the body

• Here it's given that the initial and tye final points are the same which means the shortest distance between these two points would simply be 0 as we need not travel any distance here

→ Displacement = 0 m

✭ Distance Covered by the Body

→ Distance = Circumference

→ Distance = 2πr

→ Distance = 2 × 22/7 × 7

→ Distance = 2 × 22

→ Distance = 44 m

Answer 2

Given:-

$\bigstar$A person starting from A and Ends at A

$\bigstar$Circular path of radius is 7 m

To Prove:-

$\bigstar$What is the distance travelled and displacement when a person standing from A and ends at A?...

Solution:-

$\bigstar$To Find Distance:-

The Distance covered is in the shape of circle.

So,

$\leadsto{ \boxed{ \boxed{ \bold{Distance \: = \:Circumference}}}}$

$\\ \leadsto{ \boxed{ \boxed{ \bold{Distance \: = \:2\pi \: r}}}}$

$\\ \leadsto{ \boxed{ \boxed{ \bold{Distance \: = \:2 \times \frac{22}{7} \times 7}}}}$

$\\ \leadsto{ \boxed{ \boxed{ \bold{Distance \: = \:2 \times 22 = 44 \: m}}}}$

$\bigstar$To Find Displacement:-

First we should know about displacement

Displacement:-

Displacement is the shortest distance between the final position and initial position if the body

$\bigstar$According to question,

A person is starting from A and ends at A .So, The Displacement is 0.

$\\ \leadsto{ \boxed{ \boxed{ \bold{Displacement\: = 0}}}}$
