It is necessary to know the magnitude and the direction of the vector.
Mainly because they aren't scalar quantities. A vector in the plane has two components, an x-component and a y-component. If you have the x and y components for each vector, you can add them separately. This is very similar to the addition of scalar quantities; what you can't add directly, of course, is their lengths. Similarly, a vector in space has three components; you can add each of the components separately.
Vector quantities include magnitude and direction.
There is no such thing as scalar and vector forces. However, there are scalar and vector QUANTITIES, and force is a vector quantity, as all forces have direction and magnitude. Scalar quantities, on the other hand, have only magnitude and no direction.
To make it easy, vector quantities have a direction aswell as a magnitude.While scalar quantities just have a magnitudeAn example of a scalar quantity is "Speed" and the vector quantity would be "Velocity"
Scalar quantities - quantities that only include magnitude Vector quantities - quantities with both magnitude and direction
It is necessary to know the magnitude and the direction of the vector.
Yes, it is a vector quantity.
Vector quantities are those that must be described with both a magnitude and direction. Scalar quantities can be described with only a single value.
Scalar quantities are defined as quantities that have only a mganitude. Vector quantities have magnitude and direction. Some example of this include Scalar Vector Mass Weight length Displacement Speed Velocity Energy Acceleration

No. Force and acceleration are vector quantities.
The square of a vector quantity is the vector magnitude times itself without a change in the orientation.
scalar quantities have magnitude only while vector quantities have both magnitude and direction. e.g.s of scalar quantities- distance, mass, temperature, speed e.g.s of vector quantities-displacement, velocity, acceleration, weight, force
Vector quantities include magnitude and direction.
Charge is not a vector.
