what is non conservative force give example?

A nonconservative force is one for which work depends on the path. Friction is an example of a nonconservative force that changes mechanical energy into thermal energy. Work Wnc done by a nonconservative force changes the mechanical energy of a system.

• Nonzero Net Force. – If the net force on an object is not zero, it is not in equilibrium (that is, a change in velocity will occur), and thus Newton's Second Law must be used to determine its motion.

Non-coplanar force system refers to the number of forces which do not remain in same plane. It is also stated as the number of forces in a system which remains in dissimilar planes.

The normal force is non-conservative, and therefore has no associated potential energy. The type of work done by the normal force, however, will depend upon the specific situation: ... Substantial deformation is a signal that the normal force has done measurable negative work (dissipating mechanical energy) on the system.

Non-conservative forces are dissipative forces such as friction or air resistance. These forces take energy away from the system as the system progresses, energy that you can't get back. These forces are path dependent; therefore it matters where the object starts and stops.

The gravitational force, spring force, magnetic force (according to some definitions, see below) and electric force (at least in a time-independent magnetic field, see Faraday's law of induction for details) are examples of conservative forces, while friction and air drag are classical examples of non-conservative ...

Friction is a nonconservative force, and there are others. Any friction-type force, like air resistance, is a nonconservative force. The energy that it removes from the system is no longer available to the system for kinetic energy.

False, because elastic forces are not always conservative. Elastic forces are conservative as long as the loading and deloading curves are coincident, even if the curves are not linear. For example, rubber.

Fundamental forces are independent, non fundamental forces can be explained in terms of fundamental forces.

Friction is a good example of a non-conservative force because if removes energy from the system so the amount of mechanical energy is not conserved.

A: Acceleration is not a force. Acceleration is actually part of the equation for force. According to Newton's 2nd Law Force=Mass x Acceleration.

In the frame of reference of the car, the mass is immobile, and thus has no acceleration. In the non-inertial frame of reference of the car, we still have the weight and tension forces exerted on the mass; these have the same magnitude and direction as in the inertial frame of reference of the ground.

: not collinear: a : not lying or acting in the same straight line noncollinear forces. b : not having a straight line in common noncollinear planes.

If a body is under the action of a force that does no net work during any closed loop, then the force is conservative. If work is done, the force is nonconservative.

If there is just one force on an object, then that force is the net force. ... For example in free fall, the net force on an object equals its weight - the one force pulling on it. If 2 forces push or pull on an object in opposite directions, and the two forces cancel each other exactly, the net force is zero.

This means that for a given gravitational field strength, the greater the mass of the object, the greater its weight. Weight is a non-contact force because gravity exerts its force through a field. An object does not need to be touching the Earth to have a weight.

If you remember any of the physics you learned in school, it's possible you may remember that there are four fundamental forces of nature. They are in no particular order gravity, electromagnetism, the weak nuclear force and the strong nuclear force.
