# A particle is moving in a circle of diameter 20m. What is its distance as per the table?

The distance is 62.8 m, 94.2 m, 125.6 m, and 157m.

1) For round 1

Since the particle will be at its initial location, displacement will be 0.

The circle's circumference will determine the distance.

distance = 2πr = 2 × 3.14 × 10

= 62.8 m

2) For round 1.5

The particle will be opposite in every way,

displacement=20 m

Distance will be 1.5 times the circumference

distance = 1.5 × 2 π r

= 1.5 × 2 × 3.14 × 10

= 94.2m

3) After round 2

As the particle will be at its initial location, displacement will be 0.

Distance will be 2 times the circumference

distance = 2 × 2 πr

=2 × 2 × 3.14 × 10

= 125.6 m

4) After 2.5 round

The particle will be diametrically opposite so

displacement=20 m

2.5 times the circumference will be the distance.

distance = 2.5 × 2 π r

= 2.5 × 2 × 3.14 × 10

= 157m

### Define Distance

• Distance is the sum of an object's movements, regardless of direction.
• The distance can be defined as the amount of space an object has covered, regardless of its starting or ending position.
• While distance and displacement appear to have the same meaning, they actually have very different definitions and implications.
• Displacement is the measurement of "how far an object is out of place," whereas distance refers to "how much ground an object has covered during its motion."

Summary:

## A particle is moving in a circle of diameter 20m. What is its distance as per the table?

A particle is moving in a circle of diameter 20m. The distance is 62.8 m, 94.2 m, 125.6 m, and 157m. The word particle indicates various types of very small objects, but this branch mainly investigates the irreducibly smallest detectable particles.
