"If two vector quantities are represented by two adjacent sides or a parallelogram then the diagonal of parallelogram will be equal to the resultant of these two vectors."
The law is used to add vectors to find the resultant of two or more vectors acting at a point.
whenever vectors act at the same time or from the same point.
Gravesand apparatus is used to determine weight of body using parallelogram law of vectors.
parallelogram method is a common way of adding two vectors
law of vectors also include the parallellogram law .
12 vectors, unless it is a parallelogram (13 if you include the null vector). If the quadrilateral is a parallelogram there will be two fewer.
As the velocities are in the same direction then addition of vectors becomes so easy. We simply add the magnitudes of the velocities. If velocities go exactly opposite, then we get the difference of their magnitudes. If velocity vectors get inclined, then we use the parallelogram law of vectors to get the resultant.
Given two vectors a and b, the area of a parallelogram formed by these vectors is:a x b = a*b * sin(theta) where theta is the angle between a and b, and where x is the norm/length/magnitude of vector x.
There is basically no difference. They are nothing more than 2 different visualizations of how we can graphically add two vectors.strictly if we say there is one and only difference is that---Triangle law of vector addition states that when 2 vectors r acting as the adjacent sides of a triangle taken in order. third side of the triangle will give the magnitude of th resultant 7 direction is in opposite order.Parallelogram law of vector addition states that if 2 vectors r acting as the adjacent sides of a parallelogram, then the diagonal of parallelogram from the point of intersection of two vectors represent their resultant magnitude & direction.
ya they just accidentally said law of vectors instead.
Triangle law of vectors or parallelogram law of vectors. Just while subtracting change the direction of the vector which is to be subtracted and add along with the one from which it is to be subtracted. Just as we change the sign and add in case of subtraction of numbers. Answer2: Vectors are added and subtracted by component. A=a1 + a2 and B=b1 + b2 then C = A + B = (a1 + b1) + (a2 + b2) = c1 + c2 .
