![]() ![]() Types of Forces in Biomechanicsīiomechanics is another one of the many vital aspects of force. Motion is a typical hero who wins every battle without any losses however, it loses the battle miserably when it comes to a particular villain known as ‘friction.’ Therefore, Friction is the force that resists all motion. All these movements are a part of the motion. It ranges from twisting a key in its lock to flowing water in a river. In other words, motion can be described as any and every kind of movement. In most cases, it is against, and several other additional factors add to the reactive force, which are initially absent in the applied force. Reactive forces are either along the force applied or against the force applied. So, the force which exists for every other force is a reactive force. Which Type of Force Exists for Every Other Force?Įvery action has an equal and opposite reaction, whether you scribble in your friend’s notebook and they do the same in your notebook or as seen in physics when there is any kind of interaction between two objects in space. ![]() X is the displacement of spring from its original position, and The faster the motion, the increased the air resistance force is. This force comes into existence when an object is moving in the air, and that air resists the force of the object and moves in the opposite direction. Θ is the angle with which the object moves upward. Θ is the angle with which the object moves downward The normal force may change depending upon the following three conditions if an additional force is acting. The amount of applied force depends upon the mass of the body/object. It refers to the force applied either by a person to an object or by an object to another object. The high viscosity of a substance indicates its high resistance.Į.g., Water moving against the body of a swimmer. It acts against the natural flow of the substance like a hurdle. ![]() The resistance between two such surfaces gives rise to fluid friction. This is only between liquid/gaseous surfaces and strictly does not involve any solids. Sliding Friction- only one side of the object is in contact.Rolling Friction- force resists the rolling motion.Į.g., Rolling of a basketball on the ground.Kinetic Friction- both solid surfaces are not in motion.Static Friction – both solid surfaces are in motion.This is only between solid surfaces and strictly does not involve any liquids or gases.ĭepending upon the varying solid surfaces that exist, it is again divided into four types. It is further classified into two types based on solid and liquid/gaseous surfaces – Position from which force it is applied.Movement of pen nip against the paper while writing.įactors that may or may not affect friction are – This type of force causes motion through contact, either directly or indirectly.Įxamples: Motion of wheels on the road of a car while driving. Since force has magnitude and direction, based on these, it is divided into two types – Change its direction with respect to the speed and shape/size of the object.Stop the motion of an already moving object.Increase or decrease the speed of an already moving object.(ii) Directional change – continues in the same route as the original or a different path.Ĭhanges in speed and direction contribute to the following results – Units: SI (Standard International) system – Newton (N)Ĭgs (Centimetre Gram Second) system – kg.m/s 2 or dyne Now, based on magnitude and direction, the force causes two things Therefore, force can also be expressed as: Magnitude is the amount of force applied while It is a vector product, as it has both magnitude and direction.Įxamples: Electric force, Nuclear force, Spring force, etc. What is Force?Īn invisible action leading to the motion of an object to a new position from its original position is called Force.
