Question

where is the displacement zero occurs in our daily life? ​

Answer 1

Answer:

Motion - zero displacement. A tram leaves the depot, travels along its route and returns back to the depot. The tram has covered a total of 80km but its displacement is 0km since it ends up where it started. A cart moves along a straight track for 50m.

Answer 2

Answer:

1) Motion - zero displacement. A tram leaves the depot, travels along its route and returns back to the depot. The tram has covered a total of 80km but its displacement is 0km since it ends up where it started. A cart moves along a straight track for 50m.

2) A simple example of zero work is when you stand holding a bag in your hands and do not move it. Your hands apply a force on the bag to balance the force of gravity exerted on it but since there is no displacement of the bag, the work done on it by you (your force) and also the gravity is zero.
