define scalar quantity and vector quantity with example
Answers
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 as a magnitude.
Answer:
DEFINITION OF SCALAR QUANTITY -
One-dimensional physical quantity described by a single element of aal quantity that only has magnitude, possibly a sign, and no other characteristics. This is in contrast to vectors, tensors, etc. which are described by several numbers that characterize their magnitude, direction and so on.
DEFINITION OF VECTOR QUANTITY -
By definition a vector quantity is a physical quantity with magnitude and direction, whereas, a scalar quantity only has magnitude. For example, displacement, force etc are vector quantity.
Explanation:
A SCALER QUANTITY -
1) A scalar quantity - is defined as the physical quantity that has only magnitude, for example, mass and electric charge.
2) Examples - Of scalar quantities include time , volume , speed, mass , temperature , distance, entropy, energy , work etc.
…
A VECTOR QUANTITY -
1) Vector quantity - is defined as the physical quantity that has both, magnitude as well as direction like force and weight.
2) Examples - Of vector quantities include acceleration , velocity , momentum , force , increase and decrease in temperature , weight etc.
