The Earth is spinning, so why don't we jump and land on a different location?
I know there are similar questions on StackExchange but I think it is different and detailed.
The earth is spinning 465 meters/second so why don't we jump and land on a different location?
I googled ...

Is it possible to detect your speed relative to light? [duplicate]
Let’s take two cases: (1) your velocity is constant and (2) you are accelerating.
(1) isn’t the answer no, like that’s a core idea of Einstein’s relativity stuff?
(2) I don’t know.

Why is throwing a bullet by hands not effective as using a gun? [duplicate]
The bullet when fired applies equal and opposite force to the Gun, (Newton's 3rd law)
Thus to keep the gun stable we apply some force which should be equal to the force applied by the bullet.
If we ...

How is the expansion of space distinguishable from objects moving away?
Suppose you are standing 5 feet (1.5 m) away from me. Then I move 10 feet (3.0 m) further away. Now you are at 15 feet (4.5 m) distance from me.
You say I moved. I say no; the space between us has ...

Principle of Relativity and the invariance of Newton's law in IRFs
Newton's law are form invariant under the coordinate substitutions:
$$
\tilde{x^{i}}=x^{i}+a^{i}
$$
This means that Newtons' equation of motion,
$$
F^{i}=m \frac{d^{2} x^{i}}{d t^{2}}
$$
(where $i=1,2,...

Solving a two-body problem using relative motion and reduced mass
I'm having a hard time trying to understand fully this topic and how reduced mass and relative velocity should be used. Let's say we have some sort of mechanical problem regarding the interaction (or ...

Any experiment for relative simultaneity?
Any introduction of relative simultaneity usually is like this :
Alice on a train car shines two beams of light towards both ends where two clock are. She sees both clocks see the light at the same ...

Why is relative velocity taken with respect to final velocity of affected object?
I am practicing a conservation of momentum question:
Two identical buggies move one after the other due to inertia (without friction) with the same velocity $v_0$. A man of mass m rides the rear ...

Relativity of bodies in motion in space
I have learnt that if we are travelling in space we have no way to tell if we are moving towards something or if it is the something that is moving towards us; to either object they judge that they ...

Induced motional EMF where the wire is stationary and the field source is moving?
If a wire is moving in a magnetic field $B$, there is a Lorentz force acting on both the postive and negative charges, separating them to create an electric field, which is a great explanation to aid ...

What is the ceiling on the perceived relative speeds of two bodies, from the point of view of a third observer? [duplicate]
What is the ceiling on the perceived relative speeds of two bodies, from the point of view of a third observer's reference frame?
We all know the ceiling on perceived speed relative to oneself is $c$. ...
