# Questions tagged [centripetal-force]

any force responsible for maintaining an object on a curved path around a fixed center. In introductory coursework this is usually "uniform circular motion" and yields several simple and useful relations. Not to be confused with the centrifugal pseudo-force experienced in an accelerated referenced frame.

### Apparent weight due to the rotation of earth

My concern here is that, if you were to calculate the apparent weight of an object due to earth's rotation at the equator, most text books use centripetal force and it works totally fine, but when it ...

### Forces involved in this circular motion system

As seen in the image, this system involves a small mass revolving attached to a string which is anchored with a larges mass. However, investigating this made me wonder how this system is in ...

### Increasing the speed of satellite to raise an orbit

Suppose we have a satellite orbiting the Earth in an elliptical-closed orbit. When the satellite reaches the perigee, its velocity is increased in the cross-radial direction. According to all the ...

### Conceptual Question: What would happen to satellites orbiting the earth if mass of earth suddenly increases? [closed]

Would the satellite crash onto the earth? If so, why, and in what kind of motion? A spiral motion sounds intuitive, but why? Or there is another possibility: will the satellite continue to execute ...

### Does the static friction act towards the center of a path when a cyclist bends?

Suppose, a cyclist is moving on a path. Now, static friction can provide the necessary centripetal force when the cyclist wants to take a turn. However, if the static friction can't provide the ...

### Why is the force we experience the normal force and not the net force?

I was doing some circular motion questions, and in every example to calculate a person's apparent weight/force that they experience, you find the normal force. For example when you're at the top of a ...
