Calculate the tidal force (the difference in gravitational force from right to left side or G(R) - G(L) ) from a person sitting next to you (approximately 1 meter away). You will need to make some estimations on mass and size of a normal person. 2) Compare the tidal force on a person from the Moon and a person standing nearby (the answers to the previous two questions). Which is greater and by how much?

2. Integrate the equations of motion for a spherical pendulum, i.e., a particle of mass m moving on the surface of a sphere of radius / in a gravitational field, with Lagrangian L = ml² -(0² + psin² 0) + mglcos 0. 2 Hint: Merely set up the integrals, do not evaluate them. You should obtain two integrals w.r.t. de: one determining t and another determining p. Express the first integral in terms of E,Ueff, m, and l. Express the second integral in terms of E,U eff, m, l, and M₂.

Two planets orbit a star. You can ignore the gravitational interactions between the planets. Planet 1 has orbital radius r₁, and planet 2 has r₂ = 4r₁ Planet 1 orbits with period T₁ Planet 2 orbits with period A. T₂ = -1/T₁ B. T₂=2T₁ C. T₂ = 4T₁ D. T₂=8T₁

The moon on Mars Phobos ( Fear) and Deimos ( Terror) are very close to the planet compared to Earth's Moon. Their orbital radii are 9,376 km and 23,463.2 km respectively. A) what is the orbital speed of Phobos to that of Deimos? B) If the period of Phobos orbits 7hr 39.2 min, what is the mass of Mars? C) Calculate the orbital period of Deimos.

4. Drag the moon to various locations in order to determine the quantitative effect of distance upon the gravitational force. Examine the effect of doubling, tripling and quadrupling the distance of separation (as measured from planet's center). Consider the planet's surface to be a distance of one Earth-radius (1 Rplama). Use the following table to record data for whole-number multiples of Rane. Separation Force (fictional units) Distance 2 R 3 R 4 R 5 R 6 R 7 R 8 R 9 R 10 R 11 R 12 R 21.1 pianet planet pianet planet planet planet planet planet planet planet planet Use your data to complete the following sentences. If the separation distance between the moon and the planet is ... increased by a factor of 2, then the Fgrav is olecredsed by a factor of a. ...

Which of the following statements about gravitational force, Fg , is not correct? a. Gravitational force is an attractive force only; it is never repulsive. b. Gravitational forces always exist in pairs of equal magnitude. c. The gravitational force between two objects depends on their separation. d. Gravitational force is the strongest of the fundamental forces.

8.) The Martian moon Deimos has an almost perfectly circular orbit, completed once every 30.3 hours at a speed of 1.35 km/s. What is the radius of its orbit? The radius of Mars is 3.39 x 106 m. What is its escape velocity? To what radius would Mars have to collapse to become a black hole?
