"Centrifugal Force" felt in a turning car
From my understanding, when you are in a turning car, assuming that you are not touching any part of the car except the seat, the frictional force from the seat is acting as the centripetal force. Is ...

Why is there a centripetal force acting on the rear wheels of a car when cornering?
There are quite a few questions about this in the general case (i.e. what is the source of the centripetal force when cornering?) but I don't understand what the origin of this force is specifically ...

Centripetal Force Acting on a Belt and Pulley System [closed]
Just a warning: I am an A Level student looking for a simple but thorough explanation. I am happy to be introduced to new ideas, but a sesquipedalian answer with formulae that aren't derived will only ...

If one "fell" from the center of a spinning space station, which was creating "gravity" by using centripetal force, what forces would one feel?
Let's imagine a grand hamster wheel in space. The wheel is very large and is constructed of the same reasonably inelastic material. It has three main features: The first is a solid disk rotating at ...

Acceleration calculation for an object with is rotating about it's COM and it's COM is revolving about another object
I am confused with Pseudo force and circular motion.
Let's say a satellite is revolving in a circular orbit about a planet (Gravity is providing the centripetal acceleration). Now, an object (say A) ...

Centripetal acceleration in rotational and translational motion
How do you find the centripetal acceleration of any point on a body performing both rotational and translational motion.
For example, in pure rolling if we find centripetal acceleration of the topmost ...

What is the centripetal force when a bar rotates about its center of mass?
Scenario 1:
The centripetal force acting on the ball towards the center of rotation is $\frac{mv^2}{r}$, where $m =$ mass of the ball, $v =$ magnitude of the instantaneous linear velocity of the ball,...

Centrifugal force effect in a rotating frame of reference
If the centrepital force doesn't exist in a rotating frame of reference, then in this frame perspective, how can we explain why a ball tied to a string following a circular motion not to be pushed ...

Friction and centripetal force [closed]
Let us imagine that some object (A car possibly) is moving in a circular path. At some point of time let's say that the driver of car made a turn in order to follow the circular motion. Now my ...

Which is true: objects keep spinning because of inertia, or objects keep spinning because of centripetal force?
I'm hoping any gravity or friction can be ignored.
I gather a spinning object is a non-inertial frame. I suppose that's because change of direction is acceleration. Continued acceleration requires ...

Why Doesn't Centripetal Force Counteract the Deflection of a Blade?
There was a similar question posted on this topic previously where it was agreed that the deflection of a rotating blade was decreased once the blade began rotating due to the centrifugal force. But I ...

Man on a railroad car [closed]
I have the following problem: (taken from Introduction to mechanics, Daniel Kleppner, problem 6.6)
A man of mass $M$ stands on a railroad car that is rounding an unbanked turn of radius $R$ at speed $...

Centrifugal Force: Why is it so real even from non-inertial frame? [closed]
I have thought about this for quite an amount of time. The questions:
(1) Suppose we tie a ball on a merry go round with a string. Now, we observe the ball from the merry go round and from the ground. ...

Does an object performing a uniform circular motion rotate even when there is no angular acceleration?
Is a tangential acceleration, and thus an angular acceleration necessary for rotation to occur? If an object in a UCM rotates then would centripetal acceleration be sufficient to induce rotation? Then,...
