A learner has a mass of 60 kilograms on Earth, where each kilogram weighs about 10 newtons. What is that learner's weight on Earth?

1. Mass is the amount of matter and is measured in kilograms. 2. Weight is the force of gravity on that mass and is measured in newtons. 3. On the surface of the Earth each kilogram of mass weighs about 10 newtons. 4. The learner has a mass of 60 kilograms. 5. So the weight is 60 multiplied by 10, which gives 600 newtons. 6. Answering 60 newtons confuses the mass number with the weight. 7. Answering 100 newtons would be the weight of a 10 kilogram object instead. _Source: Siyavula Natural Sciences Grade 7 (CC BY 4.0), Weight_
