1. The problem statement, all variables and given/known data Angular displacement, angular speed, , magnetic flux, electric potential, E.M.F., P.D., gravitational potential, stress,inductance. Which are the scalars and vectors? 2. Relevant equations Scalars are quantities, which have magnitude only, whereas vectors have both magnitude and directions. 3. The attempt at a solution I personally think, angular speed, electric potential, P.D, stress are scalars, but confused about others.
