Question

which of the following are the correct units for force? choose all that apply. oz dyn n kg kg·m/s lb kg·m/s² tons

Explanation:

Step1: Recall the formula for force

Force \(F = ma\), where \(m\) is mass (\(kg\)) and \(a\) is acceleration (\(m/s^{2}\)). So \(F\) has units \(kg\cdot m/s^{2}\), which is defined as \(1\) Newton (\(N\)).

Step2: Consider other units

• Ounce (\(oz\)) and pound (\(lb\)) are units of force in the imperial system.
• Dyne (\(dyn\)) is a unit of force in the CGS system (\(1\ dyn=1\ g\cdot cm/s^{2}\)).
• \(kg\) is a unit of mass.
• \(kg\cdot m/s\) is a unit of momentum (\(p = mv\)).
• Tons is a unit of mass.

Answer:

oz, dyn, N, lb, \(kg\cdot m/s^{2}\)
