How velocity= displacement per unit time ?Explain in detail
Answers
For example a car is moving in a straight path with velocity 'v' and it's not returning to its initial position so that it's displacement will be 0, it goes on and on in a straight path. Therefore it produces some displacement per unit time.Velocity is also called rate of change of displacement which means the same and it can be found by the formula displacement upon time.By the way it's called so because some other reason.I hope If you have heard ABOUT scalar and vector quantities. THEREFORE,it's all about that..
If you don't understand here no need to worry..scales are those quantity which only have magnitudes not direction but vectors are those quantities who have these both things. Therefore by referring this you will be able to understand, now see speed of an object only tells us magnitude but velocity tells us both.now you will say that a question never tells us a direction but magnitudes only whether velocity is given or not.But here is an EXAM TIP for that it's : In exams you will be given but of the quantities velocity and speed interchangeably.
now it's the same with distance and displacement distance is a scalar whereas displacement is vector.here you will have to use your same exam tip and also for it its so that the direction is not given to will use the scalar quantity formula to find the vector quantity answer.By simple words they are scalar and vector pairs of each other.
Now let's go to the point,
So as velocity is vector and so I displacement.also as speed and distance are scalar.
Therefore as we know speed is distance travelled per unit time so same we will say for velocity that velocityis displacement produced per unit time.
because for vector answers we need vector quantities and scalar answers we need scalar quantities.
Hope it helps....
