A force that is directed towards the center of a circle that keeps an object moving in that circle is called a centripetal force. Learn more about it's definition, issues, Newton's first law, examples and equations. Related to this QuestionWhat provides the centripetal force when a car driv...
Answer to: The pilot has a mass of 81400 grams. What is the resulting force the pilot feels when they just begin to pull up into the circle (they...
What provides the centripetal force when a car drives in a circle? During a NASCAR race a car goes 82 m/s around a curved section of track that has a radius of 280 m. What is the car's acceleration? What force is used to make Maglev trains run along their tracks?...

As another example, the sun'sgravityprovides the centripetal force that keeps the planets rotating around our central star. Centrifugal force describes the feeling you get when rounding a corner in a car or when an airplane banks into a turn. Centrifugal force occurs in the spin cycle of a ...
centripetal acceleration is closely related to thecentripetal force. According to Newton’s laws, centripetal force is equal to centripetal acceleration multiplied by the mass of the object. In other words, centripetal force is the total force acting on an object that causes it to move in a ...
