Inertia is a tensor quantity, which means it has both magnitude and direction. It is not solely a vector or scalar.

A kilogram is a scalar quantity because it only has magnitude and no direction associated with it. It is simply a measure of mass.
Inertia is a scalar quantity. It is a measure of an object's resistance to changes in its state of motion and is directly proportional to its mass. Inertia does not have a direction associated with it, so it is considered a scalar.
Is moment scalar or vector and why? Scalar has magnitude, but no direction. Vector has magitude and direction. Speed is a scalar. The car's speed is 25mi/hr. No direction is mentioned. Velocity is a vector. The car is traveling 25 mi/hr 20º North of East. Velocity is a vector, because it has magnitude and direction Moment has two meanings Moment of inertia = ∑ Mass* raidus^2 This moment measures how difficult it is to rotate an object. This moment is a scalar. Moment can also mean torque. Torque = Force x distance* sinθ (cross product). However torque can be clockwise or counter-clockwise. So torque is a vector.
Yes, angular momentum is a vector quantity. It has both magnitude and direction, with the direction given by the right-hand rule for rotating systems.
Electric current is not a vector quantity because it does not have a specific direction associated with it. It is a scalar quantity that represents the flow of electric charge through a conductor. The direction of current flow is defined by the convention of positive charge flow from higher potential to lower potential.
