Units and Dimension

Dimension

•Length, Mass, Time• [ L ] , [ M ] , [ T ]

Dimensional Analysis

•Check the correctness•Arrive at a formula

Example 1

The magnitude of the centripetal force Fc acting on an object is a function of mass M of the object, its velocity v, and the radius r of the circular path. By the method of dimensional analysis, find an expression for the centripetal force!

Solusinya adalahFc = (m.v2)/r
