Question

question 5 (1 point)
which of the following are units for force?
□ a kg.m
□ b newton
□ c kg.m/s^2
□ d kg/ms^2

Explanation:

Step1: Recall Newton's second law

According to \(F = ma\) (where \(F\) is force, \(m\) is mass, and \(a\) is acceleration). The SI unit of mass \(m\) is kilogram (\(kg\)), and the SI unit of acceleration \(a\) is \(m/s^{2}\). Substituting into the formula, the unit of force \(F\) is \(kg\cdot m/s^{2}\).

Step2: Define the Newton

By definition, \(1\) Newton (\(N\)) is equal to \(1\ kg\cdot m/s^{2}\).

Answer:

B. Newton, C. \(Kg.m/s^{2}\)
