Webb14 juni 2024 · It's common for working physicists to refer interchangeably to a particle's mass and its equivalent rest-energy, using the relation E = m c 2. In this picture the mass unit is the e V / c 2, an electron-volt divided by the square of the speed of light. The electron-volt, like the dalton, is a non-SI unit that's approved for use with the SI.

WebbThe SI unit for work is the joule ( J ), and its dimensions are kg•m2/s2. Another way to understand it is that one joule is equivalent to the amount of energy transferred when one newton of force moves an object a distance of one meter. Formula For Work Whenever a force moves an object, we say that work has been done. WebbA Newton B Gram C kilogram D Ns 2/m Easy Solution Verified by Toppr Correct option is A) We know that f=ma Now, for f, the S.I unit is Newton, for acceleration is m/s 2 S.I unit of (F/a) will be (N/ms 2) But, αF=mass So, Ns 2/m=kg Since, kg is the S.I unit of mass ∴ Newton is the correct answer.
