Question

Name the physical quantity which gives us an idea of how slow or fast a body is moving.

Answer 1

hey mate!

its the time that gives us the idea of comparing two objects which is fast and which one is slow.

Like you can take an example : if two objects are travelling a distance of some x meters. object a finishes the path at time 20 mins and object b reaches at time 30 mins. so here object a is faster than b based on time period. As u mentioned physical quantity time is the answer.
