What is the relationship between gravitation, centripetal and centrifugal force on the Earth?
I'm trying to analyze a situation wherein a ship is moving across the surface of the earth. I am trying to analyze this situation in a reference frame that is rotating with the earth (NED frame).
I am ...

Two particles rotating about their center of mass
Two bodies each of mass $m$ are rotating about their center of mass where the radius is $r$.
Here centripetal force of each body is $\frac{mv^2}{r}$ where $v$ is the linear speed. Now, gravitational ...

Drawing a free-body diagram for a body residing on Lagrange point $L_4$ and $L_5$
I am aware of the fact that Lagrange points $L_4$ and $L_5$ are stable equilibrium points however I cannot understand why they are equilibrium points in the first place.
Consider a Earth-Moon system ...

Will the water stay in a falling glass?
Everyday experience tells me that a glass filled with water will fall and smash on the ground as a whole object as it started (water and glass together), given that it falls face up and it does not ...

What is G-Force?
Can you explain me what is the G-Force? I always thought it was the force caused by the gravitational acceleration.. But I just saw on myth busters that they calculated the g-force on a belt during a ...

$G$-Force on falling object?
I'm trying to understand how G-Force is calculated, specifically with drop tests but also generally.
If an object is sitting on a table it has a G-Force of 1. i.e. it has 9.81m/s^2 of acceleration ...

Centripetal force on the surface of earth
Initially, I was looking for how centripetal force is produced on the surface of the rotating earth for a mass kept at any latitude. I went through the following threads -
Which force provides the ...

Centrifugal force has always been a nightmare to me
Suppose I'm in a rotating space station (that is somewhere in free space) and there is no other force. Now how am I supposed to fall to the circumference of the station if nothing pulls me? I will ...

Which force provides the centripetal acceleration that makes objects on earth's surface rotate about Earth's axis of rotation?
Let's say an object is at rest in Earth's reference frame. We know that Earth's reference frame is non inertial. If we were to observe that object from an inertial frame, we would see three forces ...

Do all bodies in a 3-body system orbit their center of mass with respect to each of the other bodies?
Scenario
Consider an empty universe with just the Earth, Moon and the Sun. The Earth and the Sun will rotate about their center of mass, which is inside the Sun. The Earth and the Moon will orbit ...

Intuitive understanding of Lagrange point L3
I learned about Lagrange points today and the physics behind L1, L2, L4 and L5 make intuitive sense to me. But I'm stumped by L3.
Wikipedia says "L3 in the Sun–Earth system exists on the opposite ...

Why is Microgravity called "Microgravity"?
I find the term "microgravity" to be misleading, how was it coined?
NASA provide this definition:
Microgravity is the condition in which people or objects appear to be
weightless. The ...
