What is the gravitational force between the earth and the satellite?

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.

What is the gravitational force between the Earth and the ISS?

The gravitational field on the ISS is approximately 89\% of that on the Earth’s surface. Of course, irrespective of these facts, the astronauts on board the ISS (and even the ISS itself) feel ‘weightless’ .

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.

Why do man made satellites not fall to Earth?

The Short Answer: Gravity—combined with the satellite’s momentum from its launch into space—cause the satellite to go into orbit above Earth, instead of falling back down to the ground.

How do you calculate the gravitational force of the Earth?

The gravitational force between a mass and the Earth is the object’s weight. Mass is considered a measure of an object’s inertia, and its weight is the force exerted on the object in a gravitational field. On the surface of the Earth, the two forces are related by the acceleration due to gravity: Fg = mg.

What is the gravitational force on a person of mass 70 kg?

706 Newtons
Why are these astronauts floating around? Let us perform a simple calculation. We will calculate the gravitational force on a 70 kg astronaut while in the ISS. On Earth, a 70 kg person weighs 706 Newtons (or 160 lbs).

Why does ISS have no gravity?

Query: In the frame of the ISS, the acceleration of any object is zero. As the ISS is accelerated towards the earth, the pseudo force will be act in the direction away from the earth. This pseudo force cancels the gravitational force acting on the objects inside the ISS.

Why does the force of gravity change the speed of a satellite when it is in an elliptical orbit but not when it is in a circular orbit?

The gravitational force changes the speed of a satellite in elliptical orbit because there is a component of the force in the direction of the satellite’s motion. 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 is the work the gravitational force does during one revolution 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.
