A vector. Since velocity is a vector, moment, which is mass x velocity, is also a vector.
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.
Magnetic moment is a vecotr quantity
Moment arm is a scalar quantity, as it represents the perpendicular distance from the axis of rotation to the line of action of a force. It does not have a direction associated with it, unlike vectors.
A scalar times a vector is a vector.
vector
Yes, you can add a scalar to a vector by adding the scalar value to each component of the vector.
Scalar
When multiplying a vector by a scalar, each component of the vector is multiplied by the scalar. This operation changes the magnitude of the vector but not its direction. Similarly, dividing a vector by a scalar involves dividing each component of the vector by the scalar.
An earthquake is neither a scalar nor a vector. It is an event.
A couple is a vector quantity because it has both magnitude (related to the moment of force) and direction (related to the axis of rotation).
A scalar multiplied by a vector involves multiplying each component of the vector by the scalar value. This operation scales the vector's magnitude while retaining its direction if the scalar is positive, or reversing its direction if the scalar is negative. The result is a new vector that has the same direction as the original (or the opposite direction if the scalar is negative) but a different magnitude.
