What is Friction? Friction is a force that causes the movement of one body to other. There are four kinds of friction: static, slipping, rolling, and liquid friction. Here are the definitions of each kind of friction as they pertain to our world of today.
Static Friction One type of static friction is a simple case of two objects touching and one of them sliding with the other. This kind of force can be described as an impulse wave or a wave pattern. For example, when two ping-pong balls are hit together, the speed of the ping-pong ball with respect to the speed of the ping-pong ball is proportional to the product of their centers of mass. This is known as the Planck’s Constant.
A second kind of Friction is caused by contact between a pair of objects. It is called rolling friction, which is also caused by the normal force of attraction or repulsion between different masses. The third kind is slip friction. This occurs when two parallel surfaces that are different from each other to allow the equalizing pressure between their surfaces to cause motion, which is then referred to as creeping.
Friction is a unique force that does not depend on the size or shape of objects. The only thing that plays a role in Friction is the speed of the moving objects. The larger the speed, the greater the Friction will be. Therefore, the larger the object, the smaller the Friction constant. When two surfaces are friction and the normal force of attraction or repulsion between the two objects exceeds the Friction constant, then a force is induced between the two surfaces that is commonly known as a Friction force.
If there is a high frequency or large amplitude of motion between two points, then the Friction constant can go high too. If a constant force is acting between two points, then the Friction constant can go high. However, if the normal force is low, then the Friction constant can also go low. So, for a given set of conditions, the Friction constant is always going to be proportional to the derivative of the kinetic, potential energy of motion. Thus, the larger the Friction constant, the smaller the potential energy that can be converted to kinetic energy.
To understand Friction better, it is important to understand how Friction works. Basically, when two smooth surfaces are sliding with respect to one another, then they will meet at some angle. This simple interaction is referred to as the Potential Difference. This potential difference is essentially the amount of force that is exerted between the two objects. This force can be described as a force or a combination of forces that can be applied to a smooth surface.
Now, let’s take a look at some more interesting examples. A bicycle wheel on a non-moving platform such as a table causes friction when it is spinning. This is due to the friction caused by the plastic wheel to the metal underneath. In another example, a jackhammer is being used to remove a statue from a wall when it comes in contact with the jackhammer’s stationary friction component, which is caused by the weight of the statue.
So, if you are wondering, “What is Friction?” You should now understand the relationship between Friction and other dynamic properties, such as lift, repulsion, gravity, thermal conductivity, and others. In addition, you should have a better idea about why lubricants are beneficial in reducing friction. All in all, you should be able to understand the concepts behind Friction better now.
