Question

We know that every derived quantity can be written in terms of some of the fundamental quantities. For
example, volume = `("length")^(3), "speed" = ("lenght")/("time")`. Using
the definitions of the following quanitities, express force in terms of fundamental quantities. Represent mass as [M], length as [L] and time as[T].
(i) Displacement = shortest distance betweenj the inital and final positions.
(ii) Velocity = `("displacement")/("time")`
(iii) Momentum = `"mass" xx "velocity"` brgt (iv) Force = `("momentum")/("time")`

Answer 1

(i) Speed = `(distance)/(time)`
(ii) [L]
(iii) `[LT^(-1)]`
(iv) `[MLT^(-1)]`
(v)`[MLT^(-2)]`
