Gravitational force

In nature, every object is attracted by every other object. This phenomenon is called gravity. The force associated with gravity is called gravitational force. The gravitational force is the weakest force that exists in nature. The gravitational force is always attractive.

Acceleration Due to Gravity

In fundamental physics, gravity or gravitational force is the universal attractive force acting between all the matters that exist or exhibit. It is the weakest known force. Therefore no internal changes in an object occurs due to this force. On the other hand, it has control over the trajectories of bodies in the solar system and in the universe due to its vast scope and universal action. The free fall of objects on Earth and the motions of celestial bodies, according to Newton, are both determined by the same force. It was Newton who put forward that the moon is held by a strong attractive force exerted by the Earth which makes it revolve in a straight line. He was sure that this force is similar to the downward force which Earth exerts on all the objects on it.

The net force on a planet is due primarily to the other planets and the Sun. By taking into account all the
forces acting on a planet, investigators calculated the orbit of cach planet.
A small discrepancy between the calculated orbit and the observed orbit of the planet Uranus was noted.
It appeared that the sum of the forces on Uranus did not equal its mass times its acceleration, unless there
was another force on the planet that was not included in the calculation. Assuming that this force was
exerted by an unobserved planet, two scientists working independently calculated where this unknown
planet must be in order to account for the discrepancy. Astronomers pointed their telescopes in the predicted
direction and found the planet we now call Neptune.

Answer the following questions: a. Daryl is given a mission to travel to the moon. He arrived at the moon and measured his weight to be 85N. If his mass is 72.5 kg, what is the gravitational acceleration to the moon? b. The gravitational pull of an object in the moon is 1/8 of that on earth. If Daryl's mass is 72.5 kg, what is his weight on the moon?
The planet Jupiter is more than 300 times as massive as Earth, so it might seem that a body on the surface of Jupiter would weigh 300 times as much as on Earth. But it so happens that a body would scarcely weigh 3 times as much on the surface of Jupiter as it would on the surface of Earth. Can you think of an explanation for why this is so? (Hint: Let the terms in the equation for gravitational force guide your thinking.)
In the law of universal gravitation, Newton assumed that the force was proportional to the product of the two masses (m1m2) . While all scientific conjectures must be experimentally verified, can you provided arguments as to why this must be? (You may wish to consider simple examples in which any other form would lead to contradictory results.)
Figure P7.45 shows a picture of American astronaut Clay Anderson experiencing weightlessness on board the International Space Station. a. Most people have the misconception that a person in a spacecraft is weightless because he or she is no longer affected by gravity. Show that this premise cannot be true by computing the gravitational field of the Earth at an altitude of 200 km the typical altitude of a spacecraft in orbit. Compare this result with the gravitational field on the surface of the Earth. b. Why would astronauts in orbit experience weightlessness even if they are experiencing a gravitational field (and therefore a gravitational force)?
An astronaut is in space with a baseball and a bowling ball. The astronaut gives both objects an equal push in the same direction. Does the baseball have the same inertia as the bowling ball? Why? Does the baseball have the same acceleration as the bowling ball from the push? Why? If both balls are traveling at the same speed, does the baseball have the same momentum as the bowling ball?

Start with the sketching of the free body diagram, formulate the differential equation, then do the manipulation.

Let's consider an astronaut with a mass of 76.0 kg standing on the Earth. What is the gravitational force (in N) on the astronaut? (Review your work from the previous part. Remember that you can use the full gravitational force formula, or w = mg.) weight on the Earth's surface = 744.8 N Now let's imagine that same astronaut in orbit aboard the space station, orbiting at an altitude (height above the Earth's surface) of 380 km. We first need to find the astronaut's distance to the center of the Earth. What is the altitude expressed in units of meters? 380 km = 380000 The radius of the Earth is 6.37 ✕ 106 m. What is the total distance (in m) from the center of the Earth to the astronaut? r =_________m Finally, let's put it all together. Use the universal gravitational force formula to find the force (in N) on the astronaut, where m = 76.0 kg, the Earth's mass ME = 5.97 ✕ 1024 kg, and the distance r is the result you just found.
