Would the distance time graph always be curved? Jul27 asked A vehicle moves from rest to a certain distance. Would the distance time graph always be curved?

Nov20 comment Why force $F$ is $ma$ but not $md$ or $mv$? How can I observe and understand “force” in real life? hmm... well, yes, it was silly me, where i am not involving the importance of time. As clearly enough, if two quantities with same mass and same displacement need to be compared for the force, then it's time, which will be deciding factor, which force is gonna be greater than the other. :) Thanks for the explanation :) Nov20 accepted Why force $F$ is $ma$ but not $md$ or $mv$? How can I observe and understand “force” in real life? Nov20 comment Why force $F$ is $ma$ but not $md$ or $mv$? How can I observe and understand “force” in real life? Well, i understand, that i cannot debate against hundreds of years of studies developed by geniuses .. but frankly what seems more intuitive to me, is that the force with which i hit, ofcourse involves the quantities like mass and displacement. But why time is important here.. is something, i need to contemplate upon! :P Nov20 comment Why force $F$ is $ma$ but not $md$ or $mv$? How can I observe and understand “force” in real life? So, if my velocity is constant, then i am not applying any force. How come this is similar to real life scenario ? Nov20 asked Why force $F$ is $ma$ but not $md$ or $mv$?

Jul12 asked Velocity is “Distance/Time” in a particular direction OR simply “Displacement/Time”? Jun6 comment What is the direction of a point vector. A vector with magnitude 0? Ya, so as per the last paragraph, a quick litmus test to know, if a quantity is vector or scalar.. is to play with it's directions. If the output of the quantity changes with directions, it's vector! Otherwise, it's scalar Jun6 awarded Commentator Jun6 comment What is the direction of a point vector. A vector with magnitude 0? Not talking about specific example. Also, "0" is something, that always produce unique results. 1/0 , 0/0 etc. What i am asking, is if their is some quantity which doesnot use direction but still is vector. eg. "distance", doesnot use direction but IS SCALAR. Likewise, any example "x", doesnot use direction but IS VECTOR ? Jun6 comment What is the direction of a point vector. A vector with magnitude 0? Any example of vector quantity, that has magnitude only, but no direction ? What i learnt is, if anything doesnot have a direction then it's scalar.
