Question

derive an expression for calculation of force​

Answer 1

Answer:

f=mv-mu/t

=m(v-u)/t

=m(a)

=ma

Answer 2

Answer:

The formula for force says force is equal to mass (m) multiplied by acceleration (a). If you have any two of the three variables, you can solve for the third. Force is measured in Newtons (N), mass in kilograms (kg), and acceleration in meters per second squared ( m/s2 ).
