$\begingroup$ psuedo force is an imaginary force which is applied on the body if the frame is non inertial,in order to use the equation F=ma.The direction of psuedo force is opposite to the direction of acceleration of non inertial observer w.r.t inertial frame.the magnitude of psuedo force=mass of the body on which it is applied*acceleration ...
This article says a change in kinetic energy (KE) remains constant in all inertial reference frames. So the kinetic energy depends upon the measurement frame of reference. But whatever inertial (non-accelerating) reference frame you use, changes of kinetic energy will be unaffected by this choice.
An inertial reference frame is one in which a particle has constant velocity if and only if has a zero net force acting on it. How can one determine if a given reference frame is inertial? For example, consider an elevator falling on earth, uniformly accelerating towards the ground. There is a man inside and can see only the interior of the ...
An inertial frame of reference can be defined in analytical terms as a frame of reference that describes time and space homogeneously, isotropically, and in a time-independent manner. Conceptually, the physics of a system in an inertial frame have no causes external to the system. Italics mine. The crucial word is conceptually. It carries after ...
A reference frame attached to the Earth surface is non-inertial, and fictitious forces need to be introduced: the centrifugal force, the Coriolis force, and the Euler force. These forces can be neglected, if they are are small, as discussed in the older version of this answer (see below).
The surface of the Earth is not, rigorously speaking, an inertial frame of reference.Objects at rest relative to Earth's surface are actually subject to a series of inertial effects, like the ficticious forces (Coriolis, centrifugal etc.) because of Earth's rotation, precession and other kinds of acceleration.
The frame that is co-moving with the International Space Station as it orbits the Earth is such a local inertial frame of reference. When you zoom out the next level is the inertial frame that is co-moving with the Earth's center of mass.
A reference frame where Newton’s second law is valid is called an inertial frame of reference. Force is absolute, so is mass(for sufficiently small speeds), so if a frame is to measure an accelera...
Wikipedia defines an inertial frame as: In classical physics and special relativity, an inertial frame of reference (also inertial reference frame or inertial frame, Galilean reference frame or inertial space) is a frame of reference that describes time and space homogeneously, isotropically, and in a time-independent manner.[1]
An inertial frame of reference is one that is not accelerating. A frame that is accelerating with respect to another inertial frame is a non-inertial frame of reference. An inertial frame moves with steady velocity in respect to other inertial frames, such that an observer within the frame can not detect any movement of the frame, unless she ...
