this is a tough question and I don't get it. It says: What factor causes the difference between weight and mass?
Since this is not my area of expertise, I searched Google under the key words "weight vs. mass" to get these possible sources:

In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search. Also see http://hanlib.sou.edu/searchtools/.
The factor that causes the difference between weight and mass is the gravitational force acting on an object. Weight is a measure of the force of gravity pulling on an object, while mass is a measure of the amount of matter in an object.
To understand this concept, let's break it down further:
1. Mass: Mass is an intrinsic property of an object and does not change with location. It is essentially the amount of matter in an object. The standard unit of mass is kilogram (kg). For instance, if you have a box of 2 kg mass, it means there are 2 kilograms of matter in the box.
2. Weight: Weight, on the other hand, depends on the gravitational field strength of a particular location. It is the force with which an object is pulled towards the center of the Earth (or any other celestial body). The unit of weight is newton (N). For example, if you hold the same 2 kg box on the Earth, it will experience a weight of approximately 19.6 N (assuming standard Earth's gravitational acceleration of 9.8 m/s²).
So, the difference between weight and mass is that weight is the force caused by gravity acting on an object, while mass is a measure of the amount of matter in an object.
To calculate weight (force), you can use the formula:
Weight = Mass × Acceleration due to Gravity
where Mass is measured in kilograms (kg) and Acceleration due to Gravity is the gravitational field strength, which on the surface of the Earth is approximately 9.8 m/s².
In summary, the factor that causes the difference between weight and mass is the gravitational force exerted on an object. Weight depends on gravity, while mass is a measure of the amount of matter.
