The magnitude of the gravitational force between the Earth and the Sun changes as the Earth moves from position 'A' to 'B' in its elliptical orbit. The force is stronger at position 'A' when the Earth is closer to the Sun, and weaker at position 'B' when the Earth is farther away from the Sun.
The magnitude of the gravitational force between the Earth and the Sun changes as the Earth moves from position 'A' to 'B' due to the elliptical shape of Earth's orbit.
In position 'A', when the Earth is closer to the Sun, the gravitational force between the two is stronger. This is because the force of gravity decreases with distance. As the Earth moves closer to the Sun, the distance between them decreases, resulting in a stronger gravitational force. The stronger force of gravity in position 'A' causes the Earth to experience a greater acceleration towards the Sun.
In position 'B', when the Earth is farther away from the Sun, the gravitational force between them is weaker. As the Earth moves away from the Sun, the distance between them increases, resulting in a weaker gravitational force. The weaker force of gravity in position 'B' causes the Earth to experience a lesser acceleration towards the Sun.
To illustrate this, let's consider an example: Imagine you have a magnet and a metal object. When the magnet and the metal object are close together, the magnetic force between them is stronger, causing the metal object to be pulled towards the magnet. However, as you move the metal object farther away from the magnet, the magnetic force between them weakens, resulting in a lesser pull on the metal object.
Similarly, in the case of the Earth and the Sun, the gravitational force follows a similar principle. The strength of the gravitational force depends on the distance between the two objects. As the Earth moves closer to the Sun, the force of gravity increases, and as it moves farther away, the force of gravity decreases.
