The weight of an object is the product of its mass, m , and the acceleration of gravity, g (where g=9.8 m/s 2 ). if an object’s mass is m=10. kg , what is its weight?

The weight of an object is the product of its mass, m, and the acceleration of gravity, g (where g=9.8 m/s2 ). Therefore, If an object’s mass is m=10 kg, its weight will be 98 Newton.

Further Explanation Mass  Mass is the amount of matter in a body or a substance. Mass is measured in kilograms and measured using a beam balance. Mass of an object or a body remains constant everywhere that is, it does not change with the gravitational pull or with the body’s location. Weight  Weight is the measure of the gravitational pull of gravity of an object. Weight is measured in Newton using a spring balance. It is a vector quantity and its direction is towards the center of the planet. Weight changes with location of a body or gravitational acceleration as it is dependent on gravity. It changes depending on the amount of gravitational pull exerted by an object on a body, such that the more the gravity the heavier the object and the less the gravity the lighter the object. Weight is given by multiplying the mass of a body by the gravitational acceleration That is; Weight = mass (M) x gravitation pull (g)

                      W = Mg  

Therefore;  

A body with a mass of 10 Kg on a surface with a gravitational acceleration of 9.8 m/s2 will have a weight equivalent to;

Weight = Mg  

             = 10 Kg x 9.8 N/m2  

              = 98 N
