2.When a force pushes or pulls the object, the object will move in the direction of the force.Force can make things move, change shape or change their speed.
3.Galileo discovered that objects that are more dense, or have more mass, fall at a faster rate than less dense objects, due to this air resistance.
4.Newton's inertia states that an object stays at rest unless acted upon an imbalanced force. Therefore, objects stay in place, because the forces acting on that object are balanced or the sum of the forces is equal to 0
The gravity is in charge of the movable objects, some objects move fast, some don't. Its all because of the weight of the item. It depends whether the item is heavy or not. If its heavy the gravity of it will most likely force a little downwards for the item since it has an extending weight. If its light, then the gravity of its weight most likely rises up and easy to move through air or anywhere.

Some objects are faster than the others because objects differ in their mass and density. For example, a brick and a plastic. If you free fall these objects from the same height and same time, the brick will reach the ground faster than the plastic. This is because the brick has more mass than the plastic.
Well, it's because the air offers much greater resistance to the falling motion of the feather than it does to the brick. ... Galileo discovered that objects that are more dense, or have more mass, fall at a faster rate than less dense objects, due to this air resistance.
