Question

If the change in position Dx is related to velocity v (with units of m/s) in the equation Dx=Av, the constant A has which dimension ?

Answer 1

Answer: seconds

Step-by-step explanation:

We have the following equation:

`Dx=A.V`

Where
`Dx` has unit of meters (
`m`) and
`V` has units of meters per second (
`m/s`).

If we input these units in the equation, we will have:

`m=A(m/s)`

Clearing
`A`:

`A=(m.s)/(m)=s`

Hence
`A` is related to time, and its unit in this case is second.
