What is the gravitational potential energy of the moon earth system is?

zero potential
The magnitude of gravitational potential energy of the moon-earth system is U with zero potential energy at infinite separation. The kinetic energy of the moon with respect to the earth is K.

What is the gravitational potential energy of the Earth moon system relative to the potential energy at infinite separation?

The magnitude of gravitational potential energy of the moon earth system is U with zero potential energy at infinite separation.

What is earth’s gravitational potential energy?

Gravitational potential energy is energy an object possesses because of its position in a gravitational field. The most common use of gravitational potential energy is for an object near the surface of the Earth where the gravitational acceleration can be assumed to be constant at about 9.8 m/s2.

What is the moon’s binding energy to Earth?

The binding energy of a smaller object, like our Moon is a tidy little 1.2 x 10^29 joules. It takes about 1800 times more energy to destroy the Earth than it takes to destroy the Moon.

What is gravitational potential energy and zero potential energy?

In this case we generally choose the zero of gravitational potential energy at infinity, since the gravitational force approaches zero at infinity. This is a logical way to define the zero since the potential energy with respect to a point at infinity tells us the energy with which an object is bound to the earth.

What is the work done by the gravitational force of sun on earth?

Answer: Work done is equal to zero assuming earth revolves around the sun in a perfect circle.

What is the gravitational binding energy of the sun?

– Gravitational energy = (3/5)GM2/R – The radius of the Sun: R = 700 million m – Gravitational energy of the Sun = 2.3 x 1041 Joules.

How is satellite binding energy calculated?

The energy required to remove the satellite from its orbit around the earth to infinity is called binding energy of the satellite. It is equal to negative of total mechanical energy of satellite in its orbit. ∴ Binding energy =|E|=gmR22r.

What is the magnitude of gravitational potential energy of the Moon?

The magnitude of gravitational potential energy of the moon-earth system is U with zero potential energy at infinite separation. The magnitude of gravitational potential energy of the moon-earth system is U with zero potential energy at infinite separation. The kinetic energy of the moon with respect to the earth is K.

What is the potential energy of a satellite in its new orbit?

It also has some initial gravitational potential energy associated with its position on the surface Ui = – = – 6.25×1010 Joules. The total energy is then given by E = T + Ui = – 1.25×1010 Joules. In its new orbit the satellite now has a potential energy U = – = – 4.6×1010 Joules.

How much tidal force does the Moon experience?

The Moon has roughly 1/4 the Earth diameter so it experiences 1/4 the tidal force (27\% actually) = (6.67 x 10 -11) x [ (5.96 x 10 24) x (7.33 x 10 22 )] / (3.84 x 10 8) 2 = 1.946 x 10 20 N Gravitational force acting between the sun and the earth is 175 times more than the gravitational force acting between the earth and the moon.

What is the mass of the Moon?

Mass of the moon, M 2 = 7.33 x 10 25 g = 7.33 x 10 22 kg The Moon has roughly 1/4 the Earth diameter so it experiences 1/4 the tidal force (27\% actually)
