The joule is equivalent to?
The joule is equivalent to?
Kg m\(^{2}\) s\(^{-1}\)
Kg\(^{2}\) m s\(^{-2}\)
Kg m\(^{2}\) s\(^{-2}\)
Kg m s\(^{-1}\)
Correct answer is C
Joule as the unit of work done or energy used.
Force = mass × acceleration
Work = Force × Distance
Work = mass x acceleration x distance
Joule = kg × \(\frac{m}{s^2}\) × m
→ kg m\(^2\) s\(^{-2}\)
