Mass is the amount of matter an object contains, whereas weight is the force acted on the object due to gravitational force. This equation may help you understand this slightly better : F=MA, in which F is the force (Weight), M is mass, and a is acceleration due to gravity, in other words 9.81 ms^-2. Since Weight is a force, it must have a direction that it acts upon. Due to the fact that weight as a force has a magnitude and direction, it’s a vector quantity in comparison to Mass, which is a scalar quantity as it only has a magnitude, not direction. Hope that was helpful!
