Vector quantities include magnitude and direction.

The three parts of a vector quantity are magnitude, direction, and orientation. Magnitude refers to the size or length of the vector, direction indicates the line along which the vector acts, and orientation specifies the starting point of the vector.
A vector quantity.
No, a scalar quantity cannot be added to a vector quantity directly. They belong to different types of quantities - scalars have only magnitude while vectors have both magnitude and direction. To add a scalar to a vector, you would need to convert the scalar to a vector by giving it a direction and then perform vector addition.
Velocity is a vector quantity.
No, electric potential is a scalar quantity, not a vector quantity.
Momentum is a vector quantity. We know that momentum is the product of mass and velocity, and velocity has direction. That makes velocity a vector quantity. And the product of a scalar quantity and a vector quantity is a vector quantity.
