Explanation:
Detailed explanation-1: -The derived unit of force is newton(N). Force is given by. F = mass x acceleration = mass x velocity / time = mass x displacement / time 2.
Detailed explanation-2: -Force equals mass multiplied by acceleration. Accordingly-by substituting the base units into the formula-we get force equals kilograms multiplied by meters divided by seconds squared. This derived unit of force is called a newton and has the symbol N. So, one newton is one kilogram-meter divided by seconds squared!
