Question

2) Write the derived units of the following (1) speed (ü) force (iii) work (iv)
pressure. [4]​

Answer 1

$\sf \huge Answer : \\ \\ \sf \red{\underline{ Force :}} \\ \sf \: formula \: of \: force = mass \times acceleration \\ \sf \:unit \: of \: force = unit \: of \: mass \times unit \: of \: acceleration \\ \sf \:force \: unit = kgm / {s}^{2} \\ \sf \: unit \: of \: force \: = newton$

$\sf \red{\underline{Work : }} \\ \\\sf \: formula \: of \: work \: done = force \times displacement \\ \sf \: unit \: of \: work = unit \: of \: force \times unit \: of \: displacement \\\sf \: unit \: of \: work =kgm/ {s}^{2} \times m \\ \sf \: unit \: of \: work = joule$

$\sf \red{\underline{ pressure :}} \\ \sf \: formula \: of \: pressure = \frac{force}{area} \\ \\ \sf \:unit \: of \: pressure = \frac{unit \: of \: force}{unit \: of \: area} \\ \\ \sf \:force \: pressure = \frac{kgm}{s {}^{2} {m}^{2} } \\ \\ \sf \: unit \: of \: pressure = kg \: / \: m {s}^{2}$
