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.
i think it is neither a vector nor a scalar but a TENSOR.
Inertia is due to mass. Mass is scalar. Hence inertia too is a scalar
A vector. Since velocity is a vector, moment, which is mass x velocity, is also a vector.
yes
Vector
vector
scalar lol
Vector is NOT a scalar. The two (vector and scalar) are different things. A vector is a quantity (measurement) in which a direction is important. A scalar is a quantity in which a direction is NOT important.
current is vector or scalar
scalar direction is a vector quantity

A vector. Since velocity is a vector, moment, which is mass x velocity, is also a vector.
Magnetic moment is a vecotr quantity
scalar lol
A scalar times a vector is a vector.

Distance is a scalar. But displacement is a vector.
