Question

is 1 newton =1kgm s-2
​

Answer 1

Where k is the constant of proportionality and it comes out to be 1 when the values are taken in SI unit. Hence the final expression will be,

F = ma

Numerical:

Suppose a body of mass 10kg is having an acceleration of 5m/s2. What is the net force experienced by it?

Solution:

From second law of motion, we know,

F = ma

Answer 2

Yes, because Force is equal to the product of mass and acceleration that is F=ma. The SI unit of mass is kilo gram and the SI unit of acceleration is m/s square and the SI unit of force is Newton that's why it is true
