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.
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
What is the centripetal force acting on the car, and which force provides it? 9. A 2.0 kg object is tied to the end of a cord and whirled in a horizontal circle of radius 4.0 m completing 2 revolutions in 6 seconds.
3 Μαρ 2024 · 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.
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.
To describe a force fully, you must state the size of the force and also the direction in which it is trying to move the object. The direction can be described in many different ways such as 'left to right', 'upwards' or 'north'. Sometimes it is useful to describe all of the forces in one direction as positive, and all of the forces in the
Velocity is a vector ∴ changing direction ⇒ acceleration ⇒ net force. The change in velocity. Δv = v2 – v1. and Δv points towards the centre of the circle. Angle between velocity vectors is. θ so. Δv.
