It's not dependent on direction; the mass of an object is the same no matter what direction the object is moving. It is the product of mass and velocity, and can only be calculated if you know how fast an object is moving (the magnitude) and in what direction. Although these two terms appear similar, their key difference is that a vector is assigned a specific direction, and a scalar is not. velocity, eg 11 metres per second (m/s) upwards. 17. which of the following is a scalar quantity, 18. which of the following is a polar vector quantity, 19.
