Questions
How is gravity affected by mass?
The larger the mass of the object, the greater the gravity
A change in motion caused by an unbalanced force acting on an object; includes increasing speed, decreasing speed, or a change in direction

What is the difference between mass and weight?
Mass is how much matter is in an object, and weight is the gravitational pull on that object
