How would earth move if the sun including its gravity suddenly disappeared? Explain your answer.

The earth would go in a straight line tangent to it's current rotation of the sun as the sun is no longer pulling it in causing the elliptical in the earths rotation. Without the gravity pulling it in, the earth would simply go flying off into space.

No it will not the sun will say the same but it will be more hot than what it is because the shadow from the earth will not be right their.

If the sun, along with its gravitational pull, were to suddenly disappear, the Earth would not instantly stop moving. This is because the Earth is already in motion due to its initial momentum when it was formed and its current orbit around the sun. The absence of the sun's gravity would, however, have significant effects on the Earth's orbit and overall motion.

Here's an explanation of how the Earth would move if the sun suddenly disappeared:

1. Initial Inertia: As mentioned earlier, the Earth already has an initial momentum from its formation. This momentum would cause the Earth to continue moving in a straight line unless acted upon by an external force.

2. Gravitational Influence of Other Celestial Bodies: While the sun is the most massive object in our solar system and has the greatest gravitational pull on the Earth, other celestial bodies such as the moon, planets, and asteroids also exert gravitational forces. These forces are much smaller compared to the sun's gravity but would still have an effect on the Earth's motion.

3. Change in Orbit: Without the sun's gravity, the Earth would no longer be under its influence and would no longer be bound to its current elliptical orbit. Instead, the Earth's path would be influenced primarily by the gravitational forces of other celestial bodies. The Earth might enter a new orbit around a different star if it is captured by its gravitational pull, or it might be expelled from the solar system altogether.

It is important to note that the sudden disappearance of the sun and its gravitational pull would have catastrophic consequences for life on Earth. Since the sun provides light, heat, and energy to sustain life, the cessation of these vital resources would have immediate and disastrous effects.
