Yes, this is correct.
true
Both of those statements are true. What's your question ?

It can be both true or false - you can treat distance as a scalar, or as a vector. If you say that (say) the distance from the cities of Cochabamba and Quillacollo is 13 kilometers - WITHOUT specifiying the direction - then it is a scalar. If you also say that Quillacollo is to the east of Cochabamba, then it is a vector.
Mass is a scalar value. Scalar refers to the magnitude of the object. Vector refers to the direction. If an object is moving, it's mass is scalar and its velocity is vectorial because the velocity has a magnitude (how fast) and a direction. Hope this helps. Search Scalar and vector for the true scientific definitions.
True, a vector quantity has direction, and a scalar quantity does not.

Yes, it's true.

TRUE. However, if you said '60 miles per hour in a northerly direction' , then that is a vector quantity. because it has direction.

True ,velocity is a vector quantity ,it is specified by a magnitude and direction.
Electrical Potential Energy is a scalar or real number. Ep = zc e2 /4pi r.Total Energy is a Quaternion, the sum of the real or potential energy and the vector energy, Ev= mcV;E = Es + Ev = zc e2 /4pi r + mcV where Ev = mcV and V is the vector velocity.
Yes momentum is a vector quantity. Because p = m v. As m is scalar and v is vector then p the momentum has to be a vector. Here m is mass and v is velocity
A "vector quantity" is any quantity where the direction matters. In the case of a force, the end result is not the same whether you and I pull an object in the same direction; in opposite directions; or perhaps at a right angle. Briefly, the direction of the force is relevant.
