Is work done independent of frame of reference?
The work done by a force is dependent on the frame of reference. Since the work done by a body is the product of work done and the displacement of the object, the work done will largely depend on the displacement of the object which depends on the frame of reference.
Why is force independent of frame of reference?
No. Force is independant of reference frame. Although you may say that Force=mass×acceleration. Since mass is constant in classical mechanics and acceleration is dependant on reference frame, so force should also be reference frame dependant.
Does the net work done on a particle depend on the choice of reference frame How does this affect the work energy principle?
Does work done depend on the frame of reference? Unequivocally, YES. Forces are the same in any inertial reference frame, but displacements are not.
What is frictional force independent of?
Frictional force is independent of the velocity of the body.
Does work done by friction depend on frame of reference?
This workdone is frictioon force time displacement. Thus work done by friction is dependent on frame of reference.
Is work done by non conservative force frame dependent?
Force does not depend on the inertial frame of the observer. That includes conservative forces. However, the work done by a force does depend on the frame.
Is work done by friction frame dependent?
Hence work done is dependent on frame of reference. Take an example of a bus. You are sitting inside the bus with a person sitting next to you. Now suppose bus starts to accelerate, but the person sitting next to you as seen by you doesn’t move i.e. it is at rest with bus frame.
Does friction depend on frame of reference?
Friction is dependent on the relative motion between the two object under contact and is independent of any reference frame (for anomalies in a non-inertial reference frame you just have to take psuedo-force into account).
What is work done by frictional force?
The work done by friction is the force of friction times the distance traveled times the cosine of the angle between the friction force and displacement; hence, this gives us a way of finding the distance traveled after the person stops pushing.
Why frictional force is independent of area of contact?
Friction is independent of the area of contact. The reason behind this is that the actual area of contact on an atomic scale is a fraction of the total surface area. If the surface area is rough then the frictional coefficient of the surface will also be larger thus will need more force to slide increasing friction.
