# Find the dimensions of1) Force2) power3) density4) momentum5) velocity

##### SOLUTION

1)      1. Force = mass x acceleration $=\ kg\ \times \ m{{s}^{-2}}\ =kg\,m{{s}^{-2}}=[M{{L}^{1}}{{T}^{-2}}]$

2)      2. Power = force x displacement/time $=\ kg\ m{{s}^{-2}}\times m{{s}^{-1}}=[M{{L}^{2}}{{T}^{-3}}]$

3)      3. Density= mass/volume $=\ {kg/{m}^{3}}=[{{M}^{1}}{{L}^{3}}{{T}^{o}}]$

4)      4. Momentum = mass x velocity  $=kg\times m{{s}^{-1}}=kg\,m{{s}^{-1}}=[ML{{T}^{-1}}]$

5)      5. Velocity = Distance/meter $=m{{s}^{-1}}=[{{M}^{o}}L{{T}^{-1}}]$
