An alternate unit for force in the SI system is?

In the International System of Units (SI), force is defined in terms of mass, acceleration, and the second law of motion as articulated by Sir Isaac Newton. This law states that force equals mass times acceleration (F = m × a).

The standard unit of force is the Newton (N). One Newton is defined as the force required to accelerate a one-kilogram mass by one meter per second squared. Hence, when we break down the units, we find that:

1 Newton (N) = 1 kg·m/s².

This means that force can be expressed equivalently as the product of mass in kilograms and acceleration in meters per second squared. Therefore, using this understanding, the alternate unit for force in the SI system is indeed kg m/s².

The other options do not represent force correctly according to SI units. For example, N/s² suggests a rate of change of force, not force itself. Similarly, N·m/s² and kg/s² do not fit the definition or dimensional analysis of force within the framework of physics and the SI metric system.
