how to know that it is scalar or vector

Answered by prt19

which have magnitude and speed both called vector

which only speed callaed scalar quantiry

amaybhatnagar13: xD

prt19: ok

amaybhatnagar13: XD

prt19: bimistake writtten

amaybhatnagar13: it happens :D

amaybhatnagar13: u in class ?

If a quantity have a magnitude only ( such as 3 kg here 3 is magnitude or to say 3 is its measurement)..and does NOT depends on directions then it is SCALAR quantity( direction here means u will not say to give 3kg sugar NORTH to a shopkeeper).such as mass..distance etc.

But is quantity depends on both magnitude and direction then it is a VECTOR quantity..such a velocity and displacement

sagar123aditya: what is distance

amaybhatnagar13: distance is length of path u traveled.

amaybhatnagar13: such as 3km 4km 3cm etc.

sagar123aditya: why weight is vector

prt19: weight is force it has magnitude and direction both

prt19: weight is 2kg may be54kg

sagar123aditya: and why momentum is vector

amaybhatnagar13: momentum of body is givin by (mass X velocity) here mass is scalar and velocity is vetor and a scalar multiplied by vector give a vector
