Question

IS K=1/2MV2 dimension less or not​

Answer 1

Answer:

since kinetic energy is also an energy

So, energy is not dimensionless.

Answer 2

Answer:

Explanation:

KINETIC ENERGY=1/2 MV²

WHERE  M  IS THE MASS AND V  IS THE VELOCITY

SINCE KE REPRESENTS KINETIC ENERGY WHICH IS A FORM OF ENERGY, THE QUANTITY IS NOT DIMENSIONLESS, BUT HAVE THE DIMENSION OF ENERGY.

THE DIMENSION OF KINETIC ENERGY IS FOUND OUT AS:

MASS=[M L^0 T^0]

VELOCITY=[M^0 L T^-1]

VELOCITY²=[M^0 L^2 T^-2]

KINETIC ENERGY=1/2 MLV²        [ 1/2 IS A CONSTANT ,HENCE IS NOT CONSIDERED]

KE=[M*L²T^-2]

HENCE K=1/2 MV² IS NOT DIMENSIONLESS.
