Centripetal force in this example? - Physics Stack Exchange
2015年1月11日 · $\begingroup$ That makes sense, so if there is only one force acting on an object then that force is the centripetal force but if there are two forces acting on an object, the only centripetal force is the net force since the object would have to be moving uniformly in a circle. So, if I had the force of gravity and the normal force acting on ...
What is the cause of centripetal/centrifugal force?
2014年2月27日 · Centripetal forces are not forces which are developed on their own; actually, it is produced under the action of different forces FOR EXAMPLE: If a man moves on a road in circular path. Centripetal force is provided by FRICTIONAL FORCE Similarly when earth moves around sun the centripetal force is provided by the gravitational force.
Is tension always the same as centripetal force?
2019年10月14日 · A centripetal force is not a particular type of force like a frictional force or a magnetic force. It's just a force that makes an object go in a circle. The word "centripetal" describes the direction of the force, not the type of force. When a car drives around in circles on level ground, the centripetal force is a frictional force.
Friction as a Centripetal Force - Physics Stack Exchange
2014年3月7日 · Frictional force opposes sliding motion, basically. Car tires produce centripetal force by changing their angle relative to the rest of the car's orientation. The tires do not slide in the direction of the tires' orientation: they roll. Friction in this direction rotates the tires, or if the engine is applying force to the wheels during the ...
The centripetal force direction on hill and valley
2022年1月18日 · What would be the object that exerts the centripetal force? In the second Newton's law $$\sum_{i} \vec{F}_i = ma$$ the left-hand side is the vector sum of the forces from the free-body diagram, and the right-hand side is the consequence (motion). In your example, the centripetal force is the consequence.
Centripetal force for a rotor or centrifugal force?
2020年7月28日 · The diameter of the tire expands until the tension force along the circumference is so large that it provides the required centripetal force. At the end of the run the tire spins down again, and in this phase there is a surplus of centripetal force, causing the tire to contract again. This is the counterpart of the expansion process: when the ...
Why does friction play the role of centripetal force during the …
What makes frictional force the centripetal force of a car turning along a curve? As friction is the opposing force and acts anti-parallel so there is no component of frictional force towards the c...
Why is the formula for Centripetal and Centrifugal force same?
2024年10月13日 · The centripetal force may come from the tension in a string or from gravity or from electrostatic attraction etc. - the source does not matter. However, if we switch to a (non-inertial) rotating reference frame in which the object appears to be stationary then we now seem to have an unbalanced force (the centripetal force) acting on a ...
Basics of centripetal force - Physics Stack Exchange
2021年8月30日 · But the centripetal force (b) makes a change on the trajectory and produces the black vector (c). If the deviation of the trajectory is the exact same length as the magenta component the trajectory is maintained as a circle. But if you imprint more centripetal force than this magenta component (d) the object will start to "fall" to the center.
Kinetic Energy and Centripetal Force - Physics Stack Exchange
2018年4月12日 · OBS OBS is may happen that the force changes anyways for changed speed because it depends on that changed distance. For example with gravity when i.e. the moon orbits Earth, the centripetal force actually does depend in distance and thus on the orbit. In such cases changing the kinetic energy may indirectly change the force.
