If an object has a mass of 10 kilograms, how much does it weigh in Newton’s?

Explanation:

Weight is the earth pull of an object to itself.

The weight of an object is defined as the force of gravity on the object and may be calculated as the mass times the acceleration of gravity.

The unit of weight is Newton and it is a vector quantity, it is directed downward vertically.

W= mg.

Where g varies but the gravity on earth is 9.81m/s² approximately.

Given that,

m=10kg, g=9.81

Then,

W=mg

W=10×9.81

W=98.1N
