acceleration in a circular motion :)
yes, this ADG helps the satellite to orbit earth. This is the centripital force
The gravitation of the central body. For example, for the Moon moving around the Earth, the centripetal force is the gravity between Earth and Moon.
The Moon's speed is very constant. There are 2 kinds of acceleration: Linear and Centripital. Centripital acceleration is experienced by a body orbiting another body, like the Moon orbits the Earth, but it does not mean speeding up.
acceleration in a circular motion :)
Because they are opposite in direction
centripital motion, gravity, friction, ect.
First, keep in mind that all objects that weigh anything have gravity - or how much they weigh (have mass). So the earth and other planets/asteroids/comets/planetesimals 'pull' on each other, their moons, if any, and on the Sun. Of course the Sun's gravity pulls all those things toward itself, too, because it has gravity. A lot of gravity.So actually, the Earth and all those other things are always 'falling' toward the Sun, and vice versa. The falling takes a different version in this case. We are familiar with acceleration in a straight line because we see it around us every day.But there is another acceleration that happens to objects in orbit.This type of acceleration is the acceleration of falling, BUT the acceleration is not the type we call 'speeding up', but the type that pushes away from the Sun (centrifugal force, or the force that makes the object (Earth) try to change to A straight line motion and fly off into space. Why doesn't the Earth just fly off into space with all that force pushing it?Well, the other 'acceleration' is called centripital acceleration - (again, not the kind associated with speed) - which results in 'centripital force', or the pulling of the Earth and Sun's gravity towards each other. Centripital force is like the "pull" on a string tied to a ball that you are whirling around. To answer your question . . . there is a very narrow orbit in which the Earth, etc, can orbit AND keep its centripital force and the opposite centrifugal force the same (balanced). And that is exactly where Earth is.There is nothing to change the Earth's orbit unless the Earth becomes much heavier or lighter, or the Sun becomes heavier or lighter. (That could happen in many billions of years) So as long as the Earth and Sun remain roughly at their current weights (masses), the Earth (or whatever) stays balanced in its orbit. The Sun doesn't 'do' anything about it . . . it just needs to exist and have gravity, which it does.KEY CONCEPT: Now, if the Earth (or whatever) or the Sun did change their mass, then the Earth would simply find a little bit smaller or larger orbit size, and be in balance, again, with slightly different centripital force and centrifugal force (but still equal to each other).
The motion would be circular characteristic of the centripital forces applied to the ball.
if you mean when they do a loop-de-loop-centripital force (centrifical force dosent exist)keeps them in their seets
Yes, the ball is accelerating because acceleration refers to any change in speed or direction of an object, regardless of whether the speed is constant. In this case, the ball is constantly changing its direction as it moves around the circular structure, leading to a change in velocity and therefore acceleration.
Centripetal force is found using the equation F=mv2/r m=mass v=velocity r=radius
The Sun's gravity is a force pulling the planet directly towards the Sun. That is always exactly balanced by the planet's acceleration, which is also towards the Sun. However the planet's momentum carries it forward in its orbit so the effect of the inward acceleration is to make the planet curve towards the Sun, and that is how the planet maintains its elliptical orbit. The above details were discovered by Isaac Newton and he was able to demonstrate why Kepler's laws of planetary motion are as they are. I won't get into centrifugal/centripetal because they are often confused.
