Question

an object is moving ina circle of radius r calculate the distance and displacement when it completes half of the circle and whe it completes one full circle

Answer 1

Explanation:

The required question answer is in the attached () picture

Check the following

Answer 2

Given:

• Object moves in a circle of radius r

To find:

Distance & Displacement for :

• Half circle
• Full circle

Calculation:

• Distance is defined as the total path length travelled by the object.

• Displacement is defined as the shortest length between the starting and the stopping point of the object.

For half circle :

• Distance = half of circumference = πr

• Displacement = diameter = 2r

For full circle:

• Distance = circumference = 2πr

• Displacement = 0 (because the starting and the stopping point of the object is same)
