Question

a newton is a unit of______. force length mass time

Explanation:

Newton is a unit in physics. According to Newton's second law \(F = ma\) (where \(F\) is force, \(m\) is mass, and \(a\) is acceleration). The unit of force is defined as \(1N=1kg\cdot m/s^{2}\), so Newton is a unit of force. Length has units like meters (\(m\)), mass has units like kilograms (\(kg\)), and time has units like seconds (\(s\)).

Answer:

force
