Question

Learning Goal: To introduce the idea of physical dimensions and to learn how to find them. Physical quantities are generally not purely numerical: They have a particular dimension or combination of dimensions associated with them. Thus, your height is not 74, but rather 74 inches, often expressed as 6 feet 2 inches. Although feet and inches are different units they have the same dimension--length.

Find the dimensions of acceleration.
Express your answer as powers of length (l), mass (m), and time (t).

Explanation / Answer

acceleration = rate of change of velocity
so dimensions of acceleration = dimension of velocity / dimensin of tome = (l/t)/t =
l/ t^2
