Question

a) State the principle of homogeneity. (1) b) Using this principle, check whether the following equation is dimensionally correct. ½ mv2 = mgh , Where m is the mass of the body, v is its velocity, g is the acceleration due to gravity and h is the height

Answer 1

Answer:

The principle of homogeneity states that the dimensions of each the terms of a dimensional equation on both sides are the same.

Using this principle the given equation will have same dimension on both sides.

On left side : h=[L], dimesion of legth
