An object has a mass of 8.00 kg what is the gravitational force on the object on earth

Weight, in physics elaborately is a type of force which pertains to the gravitational attraction of the earth and the mass of the object.

Hence, the formula for weight is mass x gravity.

Mathematically - w = m x g

Solution:
Mass = 8 kg
Gravity = 10 m/s2

Weight = 10 x 8
Weight = 80 kg*m/s2 or 80N

Therefore the weight of the 8 kg object is 80 newton.
