Answer 1

Answer:

a.when objects cover half round

distance= 1/2 of 2πr

=πr

displacement=2r

b.when it covers one round

distance=2πr

displacement=0

Answer 2

• Distance : The length of the total path coveted is called as distance.
• Displacement : The shortest distance between two points is called as the displacement.

━━━━━━━━━━━━━━━━━━━━━━━━━

a) When it completes half a round :-

• Distance : Circumference/2

→ 2πr/2

→ πr

• Displacement : Diameter

→ 2 × Radius

→ 2r

b) When it completes one full round :-

• Distance : Circumference

→ 2πr

• Displacement : 0

→ Displacement is zero because the car is at the initial position and so it is the shortest distance.
