Yes, this is a very general law. However, this doesn't mean the energy is invariant under change in reference frame. Each frame assigns a different energy to the system, but if you stay in that frame, the energy will stay constant.

What is the difference between inertial reference frame and absolute reference frame?
An inertial frame of reference = constant vel. non inertial frame of reference = acceleration
Is earth inertial or noninertial frame?
Non inertial
Does the work done by the net force acting on a particle depend on the inertial reference frame of the observer.does the change in kinetic energy so dependent if so?
When you lift a brick and throw it, nobody asks which inertial frame of reference you are using. No.
Is earth an inertial frame of reference?
Is earth an inertia or non inertial frame of reference? plz do reply as soon as possible
Is the inertial reference frame an absolute reference frame?
the inertial reference frame is not absolute. because motion is not absolute. motion is relative depends on who's looking/observing.
Difference between inertial frame of reference and non-inertial frame of reference?
An inertial frame of reference (FOR) is a non-accelerating FOR , for example if a person is observing a moving car while at rest or while moving at constant velocity, he is in an inertial FOR. A non-inertial frame of reference is an accelerating FOR for example a rotating FOR. ( Rotation requires centripetal force and centripetal acceleration so any rotating object always requires a centripetal acceleration to rotate.)
Why newton's laws are not valid in non inertial frame of reference?
newtons laws are always valid in non inertial frames
Does angular momentum requires an inertial frame?
nope...itz not necessary that the frame should be inertial....the only necesarry condition is that the TOTAL EXTERNAL TORQUE acting ABOUT THE REFERENCE AXIS should be ZERO...
Is the satellites move in inertial frame?
Yes, a satellite orbiting a planet, such as Earth, is in an inertial reference frame. This is puzzling because the satellite is not moving in a straight line. Doesn't that mean it is accelerated to curve its path circling the Earth? The only reliable way of determining whether or not you are in an inertial frame is by detection of a force that prevents you from floating freely in your space ship. If you are floating freely, as you would in the orbiting International Space Station (a big satellite), then you are in an inertial frame. If you are able to sit or stand unrestrained in your space ship then the ship is undergoing some sort of an acceleration. This really has nothing to do with your trajectory since, for example, you can speed up or slow down on a "straight line" and feel the force of acceleration. The only straight line that can be used to define an inertial frame is the geodesic path described in Einstein's General Theory of Relativity.
Is centrifugal acceleration a uniform acceleration?
In the rotating frame, it can be (though it doesn't have to be). In an inertial frame, no (though it can be uniform in magnitude).
Why earth is considered as an inertial frame of reference although it is rotating?
Because we're rotating with it
What does the theory of special relativity say about the equivalence of different frames of reference?
It says that the speed of light in a vacuum measured in any inertial frame of reference is equivalent to the speed of light in a vacuum measured in any other inertial frame of reference.
