A vector is a quantity with both magnitude (strength) and direction. Like a force having a strength in pounds and a direction. Or a wind having magnitude (in mph) and direction (Northeast). A scalar has only magnitude. Like the length of a segment or amount of peanuts in a jar. Scalars are just numbers.
The only difference is direction or directivity. A scalar quantity of anything has a magnitude or "amount" associated with it, and a vector quantity has that same magnitude or "amount" associated plus a direction or directivity.
A quantity is a vector if its direction makes a difference, like force and speed.
A quantity is a scalar if its direction doesn't make any difference, like temperature and price.
Answer2: The difference between a vector and a scalar is the angle.
Numbers in Physics are scalars and vectors. Both scalars and vectors are parts of a quaternion. Quaternions consist of a scalar and a three vectors, Q = w + Ix + Jy + Kz = |Q|(cos(Q) + v Sin(Q)) . Real and complex numbers are subsets of quaternions. The difference between a vector and a scalar is the angle of Q. If he angle is a even multiple of 90 degrees, the quaternion is a scalar; positive scalars are multiples of 4 and negative scalars are multiples of 2. If the angle is an odd multiple of 90 degrees, the quaternion is a vector.
If the angle is not a multiple of 90 degrees, the number is both a scalar and a vector. It is likely that most quantities in physics are quaternions with both scalar and vector parts.
The scalar and vector potentials are part of a Quaternion potential, Ms +Mv. Ms is a scalar and Mv is a vector (3D). The vector is the axis of the Potential and Ms denotes the Angle of rotation around the axis. If the angle is 90 degrees Ms =0 and the Quaternion is a Fermion. If the axis is zero, the Quaternion is a Boson. The angle of the Potential is ArcTan Mv/Ms.
Physics vectors and scalars are in fact, Quaternions!
It is scalar.
Scalar
a good example of vector quantity is force
give the answer
Electric potential is a scalar.
a vector drive is vertical, a scalar is horizontal.
let A be the Vector potential and Q as the scalar potential
The force is just one aspect of magnetism. For example, there is a magnetic field all around a magnet. Of course they are related, but "magnetism" is a wider term for the entire phenomenon - it may relate to the force, to the magnetic field, or to a few other things.
Gravitational potential energy is a scalar. Gravity also has a vector energy cmV= cP.
Electric potential is a scalar.
there is no difference
a vector drive is vertical, a scalar is horizontal.
let A be the Vector potential and Q as the scalar potential
it is scalar
An electromagnetic four-potential is a relativistic vector function from which the electromagnetic field can be derived. It combines both an electric scalar potential and a magnetic vector potential into a single four-vector.

Direction. A scalar has only magnitude, while a vector has both magnitude and direction.
Yes.
