Question: how many newtons does a 10 kg box weigh?
Answer: Originally Answered: If an object has a mass of 10 kg, how much does it weigh in Newton? Weight = Mass x Acceleration due to gravity. As we are talking about the weight of the object on Earth (I assume),the Acceleration due to gravity will be 9.8 m/s² . Therefore the weight of the object is 98 newtons.
