what two factors combine to give a person weight on Earth?
The two factors that combine to give a person weight on Earth are mass and gravity. Mass refers to the amount of matter present in an object, while gravity is the force of attraction between two objects due to their mass.
To calculate the weight of a person on Earth, you can use the formula:
Weight = mass × acceleration due to gravity
On Earth, the acceleration due to gravity is approximately 9.8 meters per second squared (m/s^2). So, if you know the mass of a person, you can multiply it by the acceleration due to gravity to find their weight.
Keep in mind that weight is different from mass. Mass is a measure of the amount of matter in an object, while weight is the force exerted on an object due to gravity. Mass is measured in kilograms (kg), while weight is measured in newtons (N) or pounds (lbs).
