If the moon in its orbit around earth behaves like a ball at the end of a string being swung above your head what forces are involved?

a centripetal force is a center-directed force that continuously changes the direction of an object to make it move in circle.

What is going to happen if you Imagine tying a string to a ball and twirling it around you how is it similar to the moon orbiting earth?
The string acts like the gravity of the earth. the circular motion of the ball imitates the orbit of he moon.
How centripetal force and gravity keep a satellite orbiting?
Once an object is set into motion in a given direction it will continue in that direction unless a force prevents it from doing so. If you swing a ball around and around on the end of a string, it goes in a circle at the end of the string. The thing that keeps the ball from flying off is the string pulling on it. If you let go of the string the ball will sail off in a straight line in the direction it was moving at the moment you release the string.The ball wants to go in a straight line, the thing that prevents that is the string pulling on it. The string is exerting a centripetal force on the ball preventing it from flying away.Just like the ball, a satellite rotating around the Earth would fly off into space in a straight line if something weren't pulling it back toward the Earth. Earth's gravity is exerting a centripetal force, pulling on it, preventing the satellite from sailing away.
How is tying a piece of string to a ball and twirling it around similar to the moon orbiting earth?
because they both rotate. If you hold the string with your and swing the ball around, the ball going around your hand is like a planet going around its star.
Why doesn't the sun fall from the sky. Shouldn't all the planets too fall along with the sun due to gravity?
If you tie a string to an object and hold the other end of the string, it will hang down from your hand towards the ground. If you swing the string around your head, the object will move upwards until it is rotating around your hand as it gets faster and faster. That speed is what allows the object to overcome the pull of gravity. Similarly, the planets are all rotating around the Sun at speeds which are fast enough to keep them from falling into it. The Sun is also spinning around the galaxy, and our galaxy is also in motion. The whole universe is in constant motion.
Why the gravitational acceleration increases if earth stops spinning?
When the earth is spinning, the rotation along with gravity creates centrifugal force. This is the same as the force that happens when you swing a yo-yo around by the string, the string is like gravity in that scenario holding the yo-yo close to you.
What will be tension in string on which two forces of 1010N act horizontally?
You've specified that the two forces act horizontally, but you've said nothing about how they're arranged relative to the string. -- Are the forces pulling in opposite directions on opposite ends of the string ? -- Are the forces both acting at the same end of the string, with the other end tied to a wall ? -- Are the forces in the same plane ? If so, is the string also in that plane ? I can give you configurations in which the forces are horizontal, and the tension in the string is anything you want between zero and 2,020 N. In fact, if both ends of the string are fastened to walls, and the horizontal forces push on the center of the string and perpendicular to it, then you can create any tension you want in the string, up to the breaking limit of the walls.
Does string theory negate the four fundamental forces?
String Theory does not negate the four fundamental forces, it explains them in another way.
What forces cause a pendulum to continue swinging?
Gravity and the tension in the string.
What are the forces acting on a chain in tension?
Weight of the chain and tension in the string
How do you find the circunference of a bowl?
You get a string that can fit around the bowl and wrap the string around it and mark where they overlap. measure the string and there is the circumfrence!
What are the forces exerted on a yoyo hanging motionless on a string?
The string n the yo yo r even in newtons I think -Cisco
How do you get the circumference of a cylinder with a string?
Wrap the string around the cylinder, mark where the end of the string touched itself, remove the string, and measure from the end of the string to the mark.
What are the examples for non conservative forces?
Non conservative forces are frictional force, air resistance, tension in a string and normal force etc.
Which type of elastic force is present in the string on a guitar?
forces can be added together only if they are
How many forces are acting on a simple pendulum?
At rest, tension in the string and weight of the bob are the two forces both equal and opposite. During its displaced position, the weight of the bod, tension of the string and restoring force all the three would act on it
What forces are acting on a hanging pen?
When a pen is hanging, two forces act on it - the upthrust and the force of tension in the string.
Why do moons not fall into the planet they are orbating?
Think of swinging a ball around and around on the end of a string. The ball will stay straight out at the end of the string. The ball stays suspended at the end of the string because the moving ball wants to go straight but it can't because the string is holding it -- keeping it from flying away. The force the string is exerting on the ball is called centripetal force.Moons rotate around their planets just as the ball swings around on the string. The planet's gravity acts as the string, holding the moon from flying off into space.
