How do you calculate the gravitational pull on the moon?

The mass of the moon is 7.35×1022Kg. Thus, the value of g on moon is g=1.625 m/s2.

How do you calculate the force of gravity between the Earth and the moon?

F= (G m(1) x m(2))/ R^2, where G is the universal gravitational constant, m(1) is the mass of the earth, m(2) is the mass of the moon, and R is the distance between them, center to center (squared).

What is the orbital velocity of a satellite at a height of 300 km above the surface of the Earth?

7.8 km/s
To stay in orbit, a satellite has to travel at a very high velocity, which depends on the height. So, typically, for a circular orbit at a height of 300 km above the Earth’s surface, a speed of 7.8 km/s (28,000 km/h) is needed. At this speed, the satellite will complete one orbit around the Earth in 90 minutes.

What is the gravitational force of the moon?

1.62 m/s²
Moon/Gravity

What is the force of gravity between the earth and mass of 1 kg placed on its surface?

This shows that Earth exerts a force of 9.8 N on a body of mass 1 kg.

What is the force of gravity between the earth and mass of 20 kg placed on its surface?

196 N
3 What is the force of gravity between the earth and mass of 20 kg placed on its surface? [Ans. 196 N]

What is the orbital speed of the satellite in KM?

Orbital speed is the speed needed to achieve the balance between gravity’s pull on the satellite and the inertia of the satellite’s motion. This is approximately 27,359 km per hour at an altitude of 242 km.

Where are gravitational forces strongest in the Earth moon system?

The gravitational attraction between the Earth and the moon is strongest on the side of the Earth that happens to be facing the moon, simply because it is closer. This attraction causes the water on this “near side” of Earth to be pulled toward the moon.
