An object with a mass of 5 kg weighs how many pounds?

Answer 1

"weight" is the force of gravity. From Newton's laws, we have F = m*a. In the MKS system, F is in Newtons, m is the mass in kg., and a is acceleration in m/sec² .

In MKS, the a for gravity is 9.8m/sec² and so the weight is 5*9.8 = 49 Newtons.
