With what values are calculations performed – with vector or scalar?

Vector quantities are a quantity that, in addition to a numerical value (modulus), also have a direction. Because of this, calculations with them are difficult. To make calculations with vector quantities, their projections on the coordinate axes are used, in the form:

Fvector = Fsin (a) + Fсos (a), where a is the angle between the force and the point of its application.

Therefore, the correct answer: calculations are performed with scalar values.
