Question

1. Differentiate scalar quantity and vector quantity with examples.
2. Differentiate distance and displacement.
3. What is Sl unit of speed?​
pls help

Answer 1

A vector quantity has a direction and a magnitude, while a scalar has only a magnitude. You can tell if a quantity is a vector by whether or not it has a direction associated with it. Example: Speed is a scalar quantity, but velocity is a vector that specifies both a direction as well .

Answer 2

Answer:

1.--Scalar quantity refers to the quantity, which has only magnitude and no direction.

--On the other hand, vector quantity implies the physical quantity which comprises of both magnitude and direction.

2.--scaler is One-dimensional quantity .

-- vector is multi dimensional quantity.

3.-- scaler -It changes with the change in their magnitude.

--vector-it changes with the change in their direction or magnitude or both.

4.--scaler follows ordinary algebra rules.

--vector follows rules of vector algebra.

5.Last but not the least,

--scalar quantity can divide another scalar

--but this cannot be done in the case of a vector quantity.

.. .....................................

Distance is a scalar quantity that refers to "how much ground an object has covered" during its motion. Displacement is a vector quantity that refers to "how far out of place an object is"; it is the object's overall change in position.

metre per second

Speed has the dimensions of distance divided by time. The SI unit of speed is the metre per second
