"WebSep 12, 2024 · We know the dimension of area is L 2. Now, the dimension of the expression πr2 is [πr2] = [π] ⋅ [r]2 = 1 ⋅ L2 = L2, since the constant π is a pure number and the radius r is a length. Therefore, πr2 has the dimension of area. Similarly, the dimension of the expression 2πr is [2πr] = [2] ⋅ [π] ⋅ [r] = 1 ⋅ 1 ⋅ L = L, " - Deriving formula using dimensional analysis

WebBasically, dimensional analysis is a method for reducing the number and complexity of experimental variables which affect a given physical phenomenon, by using a sort of compacting technique. If a phenomenon depends upon n dimensional variables, di-mensional analysis will reduce the problem to only k dimensionless variables, where WebSep 2, 2024 · Fg = G * m * mE / r2. Fg is the force of gravity - newtons (N) or kg * m / s 2. G is the gravitational constant and your teacher kindly provided you with the value of G, which is measured in N * m 2 / kg 2. m & mE are mass of the object and Earth, respectively - kg. r is the distance between the center of gravity of the objects - m.
