How does the mass of objects affect the gravitational attraction between them?

The larger the masses of the objects, the greater the gravitational attraction between them.

What is the difference between mass and weight?

Mass is the quantity of matter in an object. It never changes and is measured in kilograms (kg).

Weight is the force created by gravity acting on a mass. It changes depending on gravity and is measured in newtons (N).
