- What is an inertial frame? - Physics Stack Exchange
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]
- What really is inertial force? - Physics Stack Exchange
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
- Whats the difference between the five masses: inertial mass . . .
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
- What is an inertial frame in terms of acceleration?
„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
- Reynolds number and inertial force - Physics Stack Exchange
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
- Inertial frames of reference - Physics Stack Exchange
The earth is only an approximate inertial frame, so is a friction less ice sheet as you yourself have said Newton's laws are only approximately valid in those frames In Special relativity also, a frame is an inertial frame if Newton's laws of motion hold good These are frames which you get only if gravity is absent
- On the definition of an inertial frame of reference
When an inertial reference frame is given, then all Newton's construction (2nd, 3rd, and force superposition principles) can be implemented and the distinction between real forces and inertial forces (they do not satisfy the 3rd principle in particular) is effective
- Why is the Earth not an inertial frame of reference?
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
