Multiple Choice

In the equation F = mg, what does m represent?

This equation links the force of gravity (weight) to how much matter is in the object. F = mg means weight equals mass times the acceleration due to gravity. The m in this formula is mass—the amount of matter in the object, typically measured in kilograms. Mass tells you how much gravitational force the object experiences, while g is about how strong gravity is. Other options don’t fit because velocity is speed with direction, time is duration, and charge is an electrical property. The product mg specifically describes weight in newtons, with mass in kilograms and g in m/s².
