Use the centripetal acceleration equation and solve for speed. Substitute values for the acceleration due to gravity on Earth and the radius of the Earth's orbit (also known as an astronomical unit). v = √ a c r

- Summary
3 Μαρ 2024 · Centripetal force is the force that acts toward the center of a circular path. The force is always perpendicular to the direction of movement. The formula for centripetal force is F c = mv 2 /r. The force pushes or pulls an object toward the center of rotation, for example, in planets orbiting the Sun, turning a car, or spinning a ball on a string.
The moon's mass is 7.35 × 1022 kg, and it moves around the earth approximately in a circle or radius 3.82 × 105 km. The time required for one revolution is 27.3 days. Calculate the centripetal force that must act on the moon.
In this lesson, we will learn how to analyze the magnitudes, directions, and sources of forces that act on objects moving along circular paths.
Define centripetal force. Can any type of force (for example, tension, gravitational force, friction, and so on) be a centripetal force? Can any combination of forces be a centripetal force? If centripetal force is directed toward the center, why do you feel that you are ‘thrown’ away from the center as a car goes around a curve? Explain.
1 Αυγ 2023 · What does centripetal force mean. How does it work & how to find it. Learn its formula with examples & diagrams. Also, learn the differences between centripetal & centrifugal forces.
The direction of a centripetal force is toward the center of curvature, the same as the direction of centripetal acceleration. According to Newton’s second law of motion, net force is mass times acceleration: net \(F = ma \).
