2017年3月22日 · 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]

2014年11月29日 · A fictitious force, also called a pseudo force,[1] d'Alembert force[2][3] or inertial force,[4][5] is an apparent force that acts on all masses whose motion is described using a non-inertial frame of reference, such as a rotating reference frame.. This makes clearer what is one inertial force in general.

Let us define the inertial mass, gravitational mass and rest mass of a particle. Inertial mass: To every particle in nature we can associate a real number with it so that the value of the number gives the measure of inertia (the amount of resistance of the particle to accelerate for a definite force applied on it) of the particle.

2024年10月2日 · „In classical physics and special relativity, an inertial frame of reference (also called inertial space, or Galilean reference frame) is a stationary or uniformly moving frame of reference.“ Wiki. The problem with this definition is the use of the words uniform and moving.

Inertial force, as the name implies is the force due to the momentum of the fluid. This is usually expressed in the momentum equation by the term $(\rho v)v$ . So, the denser a fluid is, and the higher its velocity, the more momentum (inertia) it has.

2019年7月17日 · 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 ...

2021年9月9日 · Yet, we often can get by treating it as an inertial reference frame (e.g., when constructing furniture, cars and buildings). In some cases we do need to take account for the effect of its rotation - e.g., in weather prediction one takes account for the Coriolis force, but we still consider the Solar system as the inertial reference frame.

2021年12月29日 · 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.

2022年2月2日 · Gravity is a field force, and thus produces no internal compression, the planet simply slides through the field, You can verify this by comparing inertial rotation and non-inertial rotation: a person on a merry go round is subject to a contact force and thus is in a state of non-inertial rotation, the greater the angular velocity, and the ...

2020年7月9日 · Only inertial frames look like Minkowski frames as used in special relativity. This is the essence of the equivalence principle, and it should be clear that only one of your formulations is correct. The standard test of an inertial frame is to use an accelerometer (you may even have one in and app for your mobile phone).
