In case of three concurrent forces acting in a plane, the body will be in equilibrium if these three forces may be completely represented by three sides of a triangle taken in order. “A group of forces which are acting at one point are called concurrent forces.”Ĭoncurrent forces are said to be in equilibrium if there is no change in the position of rest or the state of uniform motion of the body on which these concurrent forces are acting.įor concurrent forces to be in equilibrium, their resultant force must be zero.

Recoiling of a gun, flight of rockets and jet planes are some simple applications of the law of conservation of linear momentum.

In other words, when no external force is applied to the system, its total momentum remains constant. The total momentum of an isolated system of particles is conserved. Impulse of a force for a given time is equal to the total change in momentum of the body during the given time. If force of an impulse is changing with time, then the impulse is measured by finding the area bound by force-time graph for that force. Impulse of a force is a vector quantity and its SI unit is 1 Nm. Impulse is defined as the product of force and the small time interval for which it acts. The linear momentum of a body is defined as the product of the mass of the body and its velocity.įorces acting for short duration are called impulsive forces. When a body A exerts a force on another body B, B exerts an equal and opposite force on A. “To every action there is equal and opposite reaction force”. When an external force is applied to a body of constant mass the force produces an acceleration, which is directly proportional to the force and inversely proportional to the mass of the body.

When we talk about accelerations produced by ‘fictitious’ or ‘pseudo’ forces, the frame of reference is a non-inertial one. I here is always a need of ‘frame of reference’ to describe and understand the motion of particle, lhc simplest ‘frame of reference’ used are known as the inertial frames.Ī frame of referent, e is known as an inertial frame it, within it, all accelerations of any particle are caused by the action of ‘real forces’ on that particle. It defines inertia, force and inertial frame of reference. A body will remain at rest or continue to move with uniform velocity unless an external force is applied to it.įirst law of motion is also referred to as the ‘Law of inertia’. Law of inertia states that a body has the inability to change its state of rest or uniform motion (i.e., a motion with constant velocity) or direction of motion by itself.Heavier the body, the inertia is more and lighter the body, lesser the inertia. The inherent property, with which a body resists any change in its state of motion is called inertia.Dynamics is the branch of physics in which we study the motion of a body by taking into consideration the cause i.e., force which produces the motion.įorce is an external cause in the form of push or pull, which produces or tries to produce motion in a body at rest, or stops/tries to stop a moving body or changes/tries to change the direction of motion of the body.Law of Motion Class 11 Notes Physics Chapter 5 Lakhmir Singh Science Class 8 Solutions.PS Verma and VK Agarwal Biology Class 9 Solutions.NCERT Solutions for Class 9 Foundation of IT.NCERT Solutions for Class 9 Social Science.
