this is aeroplane one
An airplane is subject to a specific kind of friction, which we call friction drag. Friction drag is the resistance of the air along the surface of the plane. The air molecules rub along the plane and actually slow it down.
this is book on table one
Static friction exists between a stationary object and the surface on which it is resting. It prevents an object from moving against the surface. Example: Static friction prevents an object like a book from falling of the desk, even if the desk is slightly tilted.
this is boy pushing box
Once static friction gives up, it allows the box to begin sliding across the floor, the frictional force acting on the box, is now the force of sliding friction exerted by the floor on the box.
Sliding Friction
It is the friction that acts on objects when they are sliding over a surface. Sliding friction is weaker than static friction. That's why it's easier to slide a piece of furniture over the floor after you start it moving than it is to get it moving in the first place.
this is submarine one
The friction that is involved with submarines is called kinetic friction. Kinetic friction is caused by the object moving in this case it is the force between the submarine and the water.
this is car one
The frictional force between the road and tire is what allows the tire to "push" off the road, thus moving the car forward (Newton's third law — the action is the pushing frictional force, the reaction is the forward movement of the car). ... It is the friction force that keeps the tires from sliding on the road.
