oh! i just realized my mistake.. i have been thinking about velocity as average velocity all this time. It's quite easy to miss the difference between the two. Most problems i have been solving has been treating av velocity as velocity.
is it possible to say that the interval of time is so small that the path becomes a straight line, so that the distance and displacement becomes equal and changing the direction of the body in that small instant isn't possible, so velocity becomes a scalar quantity?
I've just started reading...
i really don't understand why everyone is saying speed is equal to the magnitude of velocity vector. Are you saying it in reference to this question, in which case you are right.
Otherwise, in a generalised situation, it seems wrong to me.
1. Two small spheres with masses m1 and m2 hang on weightless, insulating threads of length L1 and L2. The two spheres carry charges of q1 and q2 (like charges) respectively. The spheres hang such that they are at the same level with one another. The threads are inclined at angle theta 1 and...
See, one thing you need to really understand while doing kinematics in one direction is the difference between distance and displacement., velocity and speed.
One way of not getting fooled by it, the one i used a lot as a beginner is to remember the definition. Now, let's look at average...
