# What is the source of centripetal force in the case of moon revolving around the Earth?

## What is the source of centripetal force in the case of moon revolving around the Earth?

ii) in motion of moon around the earth centripetal force is provided by the gravitational force on moon due to the earth.

## What is the centripetal force of the Moon?

With gravity providing a centripetal force, that path is curved towards the Earth, resulting in a roughly circular orbit. In essence the moon is in continuous freefall towards the Earth.

What makes the Moon to move in a circular orbit around the Earth?

The Moon keeps moving in its circular orbit around Earth because the force of gravity between Earth and the Moon acts like an invisible tether. If there were no gravity, the Moon would fly off into space. If the Moon stopped moving, it would crash down to Earth.

### What provides the centripetal force in the following cases?

Answer: i Gravitational force acting on the planet and the sun provides the necessary centripetal force. ii Force of gravity due to earth on the moon provides centripetal force. iii Electrostatic force attraction between the electron and the proton provides the necessary centripetal force.

### What provides the necessary centripetal force for the motion of I moon around the earth II electrons revolving around the nucleus?

Answer: The charge of the nucleus is positive and the charge of the electron is negative. There exists an electrostatic force between the positive nucleus and negative electrons. This electrostatic force supplies the necessary centripetal force for revolving of electrons around the nucleus.

What is the centripetal force acting on the moon How would the motion of the moon change if there were no centripetal force acting on it?

How would the motion of the moon change if there were no centripetal force acting on it? Gravity. If there was no gravity the moon would float away.

#### Which force is responsible for these orbiting motions?

That is to say, a satellite is an object upon which the only force is gravity. Once launched into orbit, the only force governing the motion of a satellite is the force of gravity. Newton was the first to theorize that a projectile launched with sufficient speed would actually orbit the earth.

#### Which force is responsible for the moon revolving around the earth Class 9?

gravitational force
The moon revolving round the earth in circular orbit is held by the gravitational force of the earth exerted on the moon.

What provides necessary centripetal force?

Gravitational force between sun and the planets provides the necessary centripetal force for the planets to move in circular orbit.

## What provides the centripetal force in the following cases electron revolving around the nucleus?

Answer: The charge of the nucleus is positive and the charge of the electron is negative. This electrostatic force supplies the necessary centripetal force for revolving of electrons around the nucleus.

## How is the centripetal force provided?

As a car makes a turn, the force of friction acting upon the turned wheels of the car provides centripetal force required for circular motion. As the centripetal force acts upon an object moving in a circle at constant speed, the force always acts inward as the velocity of the object is directed tangent to the circle.

How is the Moon’s orbit related to gravity?

With gravity providing a centripetal force, that path is curved towards the Earth, resulting in a roughly circular orbit. In essence the moon is in continuous freefall towards the Earth.

### Why is there no centripetal force on the Moon?

It is the curvature of spacetime. A geodesic in curved spacetime is not a straight line, it is a curve. So, there is no force acting between the Earth and the Moon. The shape of the Moon’s orbit is the shape of the geodesic of the Moon travelling through the curved spacetime caused by the Earth’s mass.

### What kind of force does the Sun and Moon have?

The Sun, Earth, moon and all other objects in the solar system attract each other with a force called gravity. This gravitational force only attracts and never repels and can act over an infinite distance.

Where does the centripetal force come from in the Solar System?

This force constantly pulls the object towards the centre of the circle. A force that pulls an object towards the centre of a circle is called centripetal force. The source for the centripetal force in the solar system is the gravitational force of the sun. Without the centripetal force from the sun the planets would travel in a straight line.
