The weight of an object and its mass are directly proportional. For a given gravitational field strength, the greater the mass of the object, the greater its weight.
weight = mass × gravitational field strength
This is when:
An apple has a mass of 100 g. Calculate its weight on Earth (g = 9.8 N/kg).
Calculate the weight of a 30 kg dog (g = 9.8 N/kg).
