# Forces (Friction)

Friction is a force. One that if often covered during our Physics Tuition classes. Friction force can be grouped into several categories according to the scenarios, and they include: i. Dry friction This is the frictional force that resists relative lateral motion between two solid surfaces in that are in contact. Dry friction is split …

The resistance offered by air in the opposite direction to that of an object with some relative speed is called air-resistance. Newton’s first law of motion This states that, ‘every object retains the state of equilibrium that it’s in, unless it’s acted upon by an unbalanced external force’. This is primarily why objects in motion …

One of the most common faced by a student while trying to solve a problem that involves rolling and friction simultaneously is to identify the direction of the frictional force. The difficulty arises from the fact that sometimes rolling friction can be deceptive to intuition. In this article, we will see various cases of rolling …

Friction is one of the most useful and one of the most troubles causing phenomenon in physics. In this article we will understand why. Firstly, let us analyze the factors that cause friction and then venture into the pros and cons of it. Thousands of years ago humankind discovered that rubbing two rocks against each …
