## What Universal Force Is Primarily Responsible For Keeping Satellites In Orbit Around Earth?

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.

## What is the force that keeps satellites around Earth?

Even when satellites are thousands of miles away, **Earth’s gravity** still tugs on them. Gravity–combined with the satellite’s momentum from its launch into space–cause the satellite go into orbit above Earth, instead of falling back down to the ground.

## How does the force due to gravity keep a satellite in orbit?

The force due to gravity keeps a satellite in orbit **by pulling it toward Earth**. By moving fast enough however, the satellite falls in a curved path and circles the Earth. So, orbit is something like a controlled fall.

## What is the centripetal force acting on 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. At this height, however, Earth’s gravity is only about 8.7 m/s^{2}.

## What universal force acts to hold the nucleus together?

**the strong nuclear force and the weak nuclear force**, act within the nucleus to hold it together.

## Which of the following is needed to keep a satellite in its orbit?

Right Lines: The satellite is taken up to its orbital height on a carrier rocket and directed out along its orbit, at a specific speed, with a rocket thrust. This speed is such that the **gravitational force**, at that height above the Earth, provides the centripetal force needed to keep the satellite in its orbital path.

## Who is the law of universal gravitation credited to?

Sir Isaac Newton

Sir Isaac Newton defined this attraction mathematically. The force of attraction between two masses is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.Sep 23, 2020

## What is the gravitational force on the man made satellite before it is launched?

Explanation: Newton worked out that, if the distance from the centre of the Earth doubles, gravity becomes **a quarter as much as it was** on the surface. A satellite with a mass of 1000 kg has a weight force of 9800 N at the Earth’s surface.

## Which of Newton’s laws helps satellites stay in orbit?

**Newton’s Third Law** is probably the best known of the three. This law is really what makes spaceflight possible. Rocket engines work by propelling exhaust out the back of the spacecraft.

## Why does the force of gravity do no work on a satellite in circular orbit?

**the force is always perpendicular to the direction of motion of the satellite**. … The force of gravity does no work on a satellite in circular orbit since the force is always perpendicular to the planet’s direction of motion.

## What provides centripetal force for the object orbiting around the planet Earth?

**The gravitational attraction of the Sun**is an inward (centripetal) force acting on Earth. This force produces the centripetal acceleration of the orbital motion.

## What are the centripetal and centrifugal accelerations acting on the satellite in its orbit?

Centripetal force is the **inward force required to** keep an object moving with a constant speed in circular path and centrifugal force is the apparent force that pulls an object from its centre or axis of rotation. It’s the fact that satellite revolving around the earth requires both centripital and centrifugal forces .

## What is meant by universal gravitation?

**every particle attracts every other particle in the universe**with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.

## Which of the following universal forces is the most effective over long distances a gravitational c strong nuclear b magnetic D Electric?

**Gravity** Acts Over Large Distances

Gravity is the weakest universal force, but it is the most effective force over long distances.

## Which universal force acts only on protons and neutrons in a nucleus quizlet?

**The strong nuclear force** is a powerful force of attraction that acts only on the neutrons and protons in the nucleus, holding them together.

## What two factors keep satellites orbiting?

A satellite maintains its orbit by balancing two factors: its velocity **(the speed it takes to travel in a straight line) and the gravitational pull that Earth has on it**.

## How do satellites stay in geostationary orbit?

**continuously staying above the same spot**. … Other orbital “sweet spots,” just beyond high Earth orbit, are the Lagrange points. At the Lagrange points, the pull of gravity from the Earth cancels out the pull of gravity from the Sun.

## What is the principle of launching a satellite?

The fundamental principle to be understood concerning satellites is that a satellite is a projectile. 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.

## Why is gravity a universal force?

**Isaac Newton** was the first to suggest that gravity is universal and affects all objects in the universe. The strength of gravity between two objects depends on two factors: the masses of the objects and the distance between them. The force of gravity between two objects is greater if the objects are closer together.

## What does the universal law of gravitation states?

Newton’s law of universal gravitation states that **two bodies in space pull on each other with a force proportional to their masses and the distance between them**. … Directly proportional to the product of two objects’ masses. Inversely proportional to the square of the distance between the objects.

## Who formulated the Universal Law of Gravitation answer?

Isaac Newton

Isaac Newton put forward the law in 1687 and used it to explain the observed motions of the planets and their moons, which had been reduced to mathematical form by Johannes Kepler early in the 17th century.

## What is the gravitational force on the satellite?

True weightlessness only occurs in deep space where the gravitational force on an object **is zero**. A satellite in a stable circular orbit around Earth is continually in free fall. As it orbits, it experiences a gravitational force towards the centre of Earth, which causes it to change direction and ‘fall’ towards Earth.

## What direction is the gravitational force of the orbiting object?

**always towards the centre of the Earth**.

## Which is experiencing a greater gravitational force the satellite or the Earth?

Which is experiencing a greater gravitational force the satellite of the Earth? **The greater an object’s mass**, the more gravitational force it exerts. So, to begin answering your question, Earth has a greater gravitational pull than the moon simply because the Earth is more massive.

## What force maintains the speed of the Earth as it moves in its orbit around the Sun?

**The centripetal force F** from the Sun pulls it into a circular path. The expression for the centripetal force is, Clearly, the centripetal force is proportional to the square of the speed of Earth around the Sun. As a result, Earth maintains its speed around the Sun.

## What are the two forces that act on the orbit of a planet?

**The gravity of the sun** and the planets works together with the inertia to create the orbits and keep them consistent. The gravity pulls the sun and the planets together, while keeping them apart. The inertia provides the tendency to maintain speed and keep moving.

## What keeps the Earth in orbit?

**The Sun’s gravitational force** is like the tetherball rope, in that it constantly pulls Earth toward it. Earth, however, like the tetherball, is traveling forward at a high rate of speed, which balances the gravitational effect. This means that the planet neither flies out into space nor falls into the Sun.

## At which point is the gravitational force on the satellite the greatest?

As a satellite orbits in an elliptical path, the force of gravitation is greatest at **the times when it is closest to the Earth**; this force causes a greater acceleration and speed of the satellite along these nearest locations of its orbit.

## What is the work done by the force of gravity on a satellite moving around the Earth in a circular orbit of radius 3500 km?

**zero**. So the satellite moving around the earth in a circular orbit, the work done is zero.

## Why does the force of gravity change the speed of a satellite in an elliptical orbit?

Why does the force of gravity change the speed of a satellite in an elliptical orbit? **Gravity slows the satellite as it moves away and speeds it up on its return.**

## What is the centripetal force that keeps satellites in orbit?

**mv**, where v is the orbital velocity of the satellite. The force of gravity that supplies this centripetal force is Gm

^{2}/r_{e}m/r

^{2}, where m

_{e}is the mass of the Earth (5.97370 × 10

^{24}kg) and m is the mass of the satellite.

## What does centripetal force act on a satellite in orbit?

This force must act **in the direction of acceleration i.e. along radius and directed towards the centre of the circle**, such a force acting on a particle performing circular motion is said to be a centripetal force.

## What provides the centripetal force to a satellite revolving around the sun?

The net force on the satellite is: … **The gravitational force** provides the necessary centripetal force.

## What is the only force acting on an object orbiting Earth?

the only force acting on the object is **gravity**.
