What is the main reason that gravitational attraction between Earth and the moon changes each day?
The daily pattern of high and low tides is not caused by the changing position of the sun and moon, but is directly caused by the rotation of the earth. Because the earth takes one day to rotate about its own axis, the high tide/low tide cycle repeats twice a day.
Which of these factors is responsible for the strength of the gravitational attraction between a planet and the Sun?
The strength of the gravitational force between two objects depends on two factors, mass and distance.
At which point is the gravitational attraction between the sun and earth the greatest?
The force of gravity is heavily influenced by the distance between two objects. In an elliptical orbit, when a planet is at its furthest point from the Sun, it is under the least amount of gravity, meaning that the force of gravity is strongest when it is closest.
What is gravitational attraction?
Definitions of gravitational attraction. (physics) the force of attraction between all masses in the universe; especially the attraction of the earth’s mass for bodies near its surface. synonyms: gravitation, gravitational force, gravity.
What is the gravitational force of attraction?
Gravitational force -an attractive force that exists between all objects with mass; an object with mass attracts another object with mass; the magnitude of the force is directly proportional to the masses of the two objects and inversely proportional to the square of the distance between the two objects.
What causes gravity Reddit?
It can be explained very easily. Gravity in a simple explanation is the effects two space bodies (in this case) have on each other. A slightly more advanced explanation is that big mass warp spacetime which doesn’t make the masses attract to each other, but rather a smaller mass being pushed towards the bigger one.
Why is the gravitational attraction between planets small?
The total gravitational pull that the object feels could be affected by other large objects nearby, but because the other planets are very far away, the strength of that gravitational attraction is extremely small and can be ignored.
In which example is the gravitational force of attraction between the two objects the greatest?
Objects that are closer together have a stronger force of gravity between them. For example, the moon is closer to Earth than it is to the more massive sun, so the force of gravity is greater between the moon and Earth than between the moon and the sun.
Which two factors affect the strength of the gravitational pull on two objects?
When dealing with the force of gravity between two objects, there are only two things that are important – mass, and distance. The force of gravity depends directly upon the masses of the two objects, and inversely on the square of the distance between them.
