Mass does not affect the acceleration of an object due to gravity. Any object of any size or mass will fall at the same speed. A ball rolling down an inclined plane is accelerated by gravity, so its speed won't be affected by its mass at all.
Yes, a gas is the same as a solid except the molecules are moving farther apart. In a solid they are bunched together.
The more massive the object is, or the faster the object is moving, the bigger the crater will be.
If the bag is sliding across the countertop (i.e., the same surface of the bag is always in contact with the counter), then no. Rolling friction is only relevant when the surface of an object in contact with the surface it moves across always changes.
Rolling friction is when an object that is rolling/sliding/moving on a surface is slowed down or stopped, because of the friction of the two objects rubbing against each other.
Moving resistance for a vehicle refers to the forces that impede its motion when in motion, such as air resistance, rolling resistance from the tires, and friction in the moving parts of the vehicle. These factors contribute to the energy needed to overcome resistance and propel the vehicle forward.

A wheel barrow has tow levers (the handles), a wheel and axle (wheel), and some people could say it is an inclined plane BUT only when it is rolling and it is tilted ti be an incline plane. When it is not moving it is a flat plane not an inclined plane. :)
moving objects between two levels
static is standing still, and rolling is movement. static is the friction that prevents the object from moving, rolling is the friction that slows down the object while it is motion.
a wedge
yes.
No, friction tends to oppose the motion of objects moving over an inclined plane, which can make them move slower rather than faster. The amount of friction between the object and the surface of the inclined plane can affect how quickly the object accelerates or decelerates while moving.
What has only one movement
The friction between a rolling object and the surface it rolls on is called rolling friction or rolling resistance. This type of friction is caused by the deformation of the rolling object and the surface as they come into contact, leading to energy loss and slowing down the object's motion.
ball will just move without rolling, staying in it's initial position but moving indefinitely (that is if it is given an initial force).
The type of friction involved in a train moving along a track is mainly rolling friction. This occurs between the wheels of the train and the tracks they roll on. Rolling friction is less than sliding friction, allowing the train to move more efficiently.
