Define: Quantities including, speed, mass, or length that are only described by magnitude (or numerical values). Length, area,density, speed, position, temperature, volume, and etc are still involved with vectors. The magnitude of a scalar is the only important thing needed to know for a scalar. The difference that is easy to tell would be as in my explain would be that a scaler finds volume, and vector finds velocity.
Example:
The scalar as displayed in this graphic shows the different quantities, where the big difference is that scalars find volume and vectors find velocity. Scalar quantities are length, area, volume, density, work, power etc; whereas vectors quantities are displacement, direction, velocity, acceleration, lift, drag, momentum, etc.
