Question

A body is moving along a circular path of radius R. What will be the distance travelled and displacement of the body when it completes a revolution?

Answer 1

Answer:

distance is equal to 2πR which is the circumference

displacement is zero

Answer 2

Solution :

⏭ Given:

✏ A body is moving along a circular path of radius R.

⏭ To Find:

✏ Distance travelled and displacement of the body after one revolution.

⏭ Concept:

✏ Distance is defined as total length of path covered by moving body and displacement is defined as the shortest distance between initial and final point.

⏭ Calculation:

• Distance travelled

✏ Distance = circumference of circle

✏ Distance = 2πR

• Displacement

✏ Displacement = 0

✏ Because inutial and final position is same.

⏭ Additional information:

• Distance travelled is scalar quantity.
• Displacement is vector quantity.
