Question

State the difference between distance and displacement.A particle is moving in a circle of diameter 20 m. What is its displacement when it completes 1.5 rounds. with steps please

Answer 1

Answer:

Displacement is the shortest distance between end point and starting point of particle( that is always length of straight line connecting these point ).

Particle completes 1.5 revolution( 1 full + 1/2)

By complete 1 revolution it comes to starting point of circle.amd after half revolution it became diametrically opposite. So displacement is 5m.

please give me 10 thanks

Answer 2

Answer:

distance in 1.5 rounds=1.5*2*pi*r

=1.5*2.22/7*10

=660/7=94.29m

displacement=10+10=20m
