A contact force, such as friction. If a car wheel wasn't on the ground there couldn't be friction. A non-contact force could be magnets, the two magnets don't need to touch to repel or attract :)

How does friction affect forward motion?
Friction is when two objects touch each other, either smooth or rough friction causes the object to slow down. Also an unbalanced force is when the net force isn't 0 which causes a object to move and cause friction other than a balanced force is when the net force is 0.

What is a force only exerted when objects touch?
A contact force? The answer really depends on the level of the question. Primary school answer: A pushing or pulling force, or a friction force occur when objects touch. High school answer: Same as above, but 'pushing' and 'pulling' would be replaced with positive and negative. Friction would be defined as a force that opposes motion, and would include air resistance and drag. University answer: Technically, there is no such force, as all forces act at a distance without touching. In fact, objects don't actually 'touch' one another at all. The outer electrons in an object's atoms will repel said electrons from another object's atoms through the electromagnetic force. This only makes it feel like the objects have come into contact with one another, when in fact they haven't.

Because it is two surfaces rubbing against each other, in this case it creates heat and possibly static electricity. To touch; contact. If two surfaces rub against each other forcefully this is a contact force.

Does air pressure in a basketball affect you free throw accuracy?
YES. It does affect your free throw accuracy. If the ball does not have enough air you will have to give the basketball more force. When more force is applied it will probably bounce off the rim. With more air you could give the ball more touch and your percent will go up.
