Question

state the main point of difference between 1. distance and displacement 2. uniform motion and non uniform motion ​

Answer 1

1.

-Distance is a scalar quantity whereas displacement is a vector quantity.

-Distance is the total length covered by an object whereas displacement is the shortest path from initial to the final position.

2.

-In Uniform motion, movement of a body is along the straight line with constant speed; whereas, in non-uniform motion, movement of a body is along the straight line with variable speed.

-In uniform motion, the body covers equal distance in equal interval of time; whereas, in non-uniform motion, the body does not cover the equal distance in equal interval of time.
