Question

why is it important to differentiate vector quantities from scalar quantities? please help.. :( PLEASE I REALLY NEED SOME HELP! :(

Answer 1

@abb0t

Answer 2

First of all, do you know the difference between vector quantity vs scalar quantity?

Answer 3

i can tell you this: distance is a vector and time is a scalar unit. came across that earlier but im just a hobbiest. gl

Answer 4

because if i told you that your phone is 50m (scalar) away from the cross marked on the map, you would have to start guess where i hide your phone.

but if i said 50m due north (vector), it's much easier.

Answer 5

Scalar quantity is quantity which has only magnitude while vector quantity is quantity which has both magnitude and direction. The direction can be expressed by using the sign + and -. It is important especially when you are calculating momentum

Answer 6

coz if we dont know given quantity is vector or scalar then in that case we can not calculate the value of things which we want to calculate directly?
supppose in triangle three charges are present and we want to calculate net force on any of the corner then if we know force is vector then we can easily calculate the force by drawing its vector diagram without any calculation otherwise we have to use law of parallelogram.
