Magnitude is a measure of the strength of a vector. It is calculated by taking the square root of the sum of the squares of the vector’s components. For example, the magnitude of the vector (3, 4) is sqrt(3^2 + 4^2) = 5.
Magnitude is an important concept in physics and engineering. It is used to calculate forces, moments, and other physical quantities. For example, the magnitude of the force of gravity is given by the equation F = Gm1m2/r^2, where G is the gravitational constant, m1 and m2 are the masses of the two objects, and r is the distance between them.
