Question

please help me for preparing notes on scaler and vector quantity for class 9th
​

Answer 1

Answer:

A vector is described by both direction and magnitude . Examples of scalar quantities include time , volume , speed, mass , temperature , distance, entropy, energy , work , … Example of vector quantities include acceleration , velocity , momentum , force , increase and decrease in temperature , weight

Answer 2

Explanation:

SCALAR :

1. it is represented only by magnitude

2. in physics, most of the quantities are scalars.

eg:Mass,time,temperature

for eg, we say mass is 5 kg that's magnitude. we don't say mass 5 kg in northwest direction (lol)

VECTORS :

1. it is represented by both magnitude and direction

2. in physics only some quantities are represented by vectors

eg:velocity,force
