Why does asteroids hit earth?

Asteroids will hit earth every now and then because of the earths gravitational pull, but we don't get as much as Jupiter seeing as it has the highest gravitation pull.


Why there is high tide during full moon?

Depending on where you live, you have high tides about every 12 hours, no matter what the phase of the Moon. However, at the full and new moons, you have higher-than-average "spring" tides, because the gravitational pull of the Moon lines up with the much lower gravitational pull of the Sun. At the quarter moons, we have lower-than-average "neap" tides because the tidal pull of the Moon and the tidal pull of the Sun are working at cross-purposes.


Why does the moon have more gravitational pull on the Earths oceans than the moon if the sun is so massive?

It is because the moon is much closer to the earth. Gravitational pull decreases in proportion to the square of the distance.


Why can you feel and see the effect of Earth's gravitational pull on you but you cannot feel or see the effect of you teacher's gravitational pull on you?

The difference lies in the mass and distance between you and your teacher. Earth is much more massive and closer to you than your teacher, so its gravitational force is much stronger. Additionally, the force is proportional to the mass of the objects involved, therefore Earth's gravitational pull has a more noticeable effect on you compared to your teacher's.


what Pluto, the dwarf planet, is 5.9 billion kilometers from the Sun. Explain how a model showing the gravitational pull on Pluto would differ from your model of Earth’s orbit.?

The distance between the Sun and Earth is 149,600,000 kilometers, and the distance between the Sun and Pluto is 5.9 billion kilometers. The gravitational pull decreases with an increase in distance. So, the gravitational pull of the Sun on Pluto is much less than its pull on Earth. So, in the model, Pluto’s orbit would have a much larger radius than Earth’s orbit.
