Question: what is the equation for weight ks3?
Answer: The weight of an object is the gravitational force between the object and the Earth. The weight of an object depends upon its mass and the gravitational field strength. On Earth, g is about 10 N/kg. This means that a 2 kg object on the Earth's surface has a weight of 20 N (2 kg × 10 N/kg = 20 N).
