Friction
Friction between two objects produces heat.
Friction between two objects produces heat.
Mass certainly affects the gravitational attraction between objects; air resistance doesn't.
This is false. The answer is that mass and distance affect the gravitational attraction between objects. Air resistance has no effect on this.
No. Objects have to be in contact for there to be friction between them.

The force that resists motion between objects that are in contact is called friction. One object can be stationary or they both can move.
gravitational forces are experience between to objects without any contact between them
I am not sure how the two objects of equal resistance are supposed to be connected. But for a current to flow, for example across a resistor, there must be a voltage difference between the terminals of this resistor.
Static and Kinetic friction, static is the friction between two objects when they are not moving (relative to each other) an example of this is and object staying still on a sloped surface. obviously, kinetic friction is the friction between two objects that are moving and making contact, for example wind resistance.
