Question

In a lab, the mass of object A is 65 kg. Object A weighs:

Answer 1

637
65 times 9.8
Mass times gravitational strength equals weight

Answer 2

Answer is: (C)- 637 N.

Gravity as a force which causes any two bodies to be attracted to each other.  

The gravitational effect increases as the size of an object increases. Earth s surrounded by its own gravitational field.

The weight of an object is the amount of force acting on the object due to gravity. SI unit for weight is newton (N).

m(object) = 65 kg.

g = 9.8 m/s²; the acceleration of free fall.

W = m·g.

W = 65 kg · 9.8 m/s².

W = 637 N; weight of the object A.
