firstly You should know what does actually a magnitude mean ?

Any physical quantites like Distance , displacement , speed , velocity , acceleration , force etc have magnitude...

Magnitude just a number here...when we talk about the magnitude of any physical quantity , we only consider its value or scale or size or number except DIRECTION...

For example : duration of a class in a school 1 Hr...

here

=> 1 is the magnitude

=> Hour is the Unit

=>1Hr. is the Physical quantity TIME

Another Example : A person walk 5 km towards EAST.

Here

=> 5 is the magnitude of displacement.

=> km is the unit

=> Towards East is the Direction

=> Physical quantity - Displacement

If you add the the direction ( towards east ) with the magnitude it becomes displacenent...And if you consider or take only magnitude i.e, 5 km only , it is what we call magnitude of displacement and also called DISTANCE...

Hope this help...

Heya! Good Morning! Keep Rocking!

Magnitude of displacement' is a technical way of saying 'distance, as measured directly between the start point and the end point'.As it includes no directional information it is a 'scalar' quantity rather than a 'vector'.Example, imagine two friends live on opposite sides of a lake. Bill intends to visit Ben. To drive around the edge of the lake is a journey of 20km. To row directly across is a journey of 2km. He doesn't feel like rowing today, so he drives the 20km - but the magnitude of his displacement is still 2km.This example is constrained to two dimensions. The same principle applies in three dimensions - that is, the magnitude of the displacement is the shortest distance between the two points.It gets more complicated when you start trying to measure things like displacement on a globe, as in navigation. It gets messy because two-dimensional rules are being applied to a three-dimensional surface. But that's another story that others are better able to tell.

Hope it helps...
