What causes centripetal acceleration?
Centripetal accelerations are brought on by centripetal forces. Any satellite’s circular motion around a celestial body, with the exception of the Earth’s rotation around the Sun, is caused by the centripetal force created by their mutual gravitational attraction.
What is the centripetal force on a satellite?
This centripetal force generates the centripetal acceleration that is required to move the satellite almost perpendicular to the radius from the center. . ,
How do satellites move in orbit without fuel?
Afterwards, there is no need for any fuel for the orbital motion of the satellite, unless some orbit correction is necessary.. This centripetal force generates the centripetal acceleration that is required to move the satellite almost perpendicular to the radius from the center. .
What is the Earth's Center Force of attraction?
Mainly, it s the Earth 's centripetal force of attraction towards its center,. The magnitudes of such attractions, from close-by Earth-orbiter Luna and the far distant Sun, are negligible. Initially, the satellite is pushed into an orbit around the Earth with some angular speed, along the tangent to the desired nearly-circular-orbit.
What provides the force that causes centripetal acceleration of a satellite in orbit?
An orbiting satellite is close enough to be acted upon by Earth's gravity. This force is constantly pulling the satellite in toward the center of the earth – it is a centripetal force and causes a centripetal acceleration.
What force causes centripetal acceleration?
Centripetal forces cause centripetal accelerations. In the special case of the Earth's circular motion around the Sun – or any satellite's circular motion around any celestial body – the centripetal force causing the motion is the result of the gravitational attraction between them.
What force keeps a satellite moving in a circular orbit?
GravityGravity is a force of attraction between masses. It provides the centripetal force needed to keep a satellite in orbit around a planet, or a planet in orbit around a star such as the Sun. The motion of the moon around the earth is due to the centripetal force.
Do satellites use centrifugal force?
When an object of mass m moves in a circular path of radius r at a velocity v, it will experience an outward centrifugal force given by the equation: For a satellite to stay in orbit, this centrifugal force must balance gravity. Thus, .
What can centripetal force be caused by?
The force toward the center, which keeps the object in orbit, is centripetal force. It can come from various sources: gravity, EM, tension in a string, etc.
What force is centripetal force?
Centripetal force is the force acting on an object in curvilinear motion directed towards the axis of rotation or centre of curvature. The unit of centripetal force is newton. The centripetal force is always directed perpendicular to the direction of the object's displacement.
What supplies the centripetal force for a satellite?
This centripetal force is supplied by gravity - the force that universally acts at a distance between any two objects that have mass. Were it not for this force, the satellite in motion would continue in motion at the same speed and in the same direction.
What are 3 examples of centripetal force?

What force provides the centripetal force needed for the car to travel around the curve?
force of frictionAs a car makes a turn, the force of friction acting upon the turned wheels of the car provides centripetal force required for circular motion.
What is centrifugal force vs centripetal force?
Centripetal force is the force REQUIRED for circular motion. Centrifugal force is the force that makes something flee from the center.
Is centripetal force equal to gravitational force?
Setting the gravity force from the universal law of gravity equal to the required centripetal force yields the description of the orbit. The orbit can be expressed in terms of the acceleration of gravity at the orbit. The force of gravity in keeping an object in circular motion is an example of centripetal force.

What provides the force that causes the centripetal acceleration of a satellite in orbit?
Answers and Replies
The force that provides the centripetal acceleration for a satellite orbiting in uniform circular motion (that is, the satellite has the same speed at every point on its orbit) is the gravitational force: Where G is the gravitational constant (this is easy to find, its probably in the cover of your text book), M E is the mass of the earth, m is the mass of the satellite, and r is the distance between the center of the Earth and the satellite. You know by Newton's Second Law that this gravitational force must equal the mass of the satellite times the centripetal acceleration, and the centripetal acceleration in terms of speed is: And so we have: And now you can solve for the speed.
