In static friction, the frictional force resists force that is applied to an object, and the object remains at rest until the force of static friction is overcome. In kinetic friction, the frictional force resists the motion of an object. ... The frictional force itself is directed oppositely to the motion of the object.
There are 2 types of frictions: 1. Rolling friction 2. Static friction 3. Fluid friction
Friction act on us every day. Types of Friction: 1) Sliding friction 2) Rolling friction 3) Static friction 4) Fluid friction
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.
static friction is greater,kcompared to all other frictions. static friction>kinematic friction>rolling friction static friction(sf) comes in to picture when we are trying to move a body from rest. the (sf) increases with force up to a extent and there after the body starts moving. this is the reason for which low gear is used to start vehicles. in first gear the total engine power is utilized to initiate the motion
Frictions
Unhelpful frictions are obstacles or barriers that impede progress, efficiency, or communication within a system or process. These can include excessive bureaucracy, conflicting instructions, lack of clarity, or outdated technology. Identifying and removing unhelpful frictions can lead to smoother operations and improved outcomes.

Drag, when referring to Air Resistance, is a type of friction. When an object flies, it comes in contact with air that it has to push out of the way. Since energy is always transferred (never created nor destroyed), the moving object loses some energy/force/velocity when rubbing against the passing air.The frictions that we are more aware of are kinetic and static friction. Static friction is what holds an object in place when another force is acting on it. For example, when you have a book on a table and slope it, the book takes a bit to start moving. However, if you hold the table at a lesser angle and touch the book lightly, it will start to move. This is the difference between static and kinetic frictions.
