Why is heavenly bodies revolves around the sun?
Heavenly bodies revolve around the Sun, by obeying the Laws of Newtonian Mechanics(Gravity). All bodies would remain stationary or in unioform(straight line/speed) motion, unless acted upon by a force. That force is the mass of of the body and the acceleration dies to gravity. As the Earth has gravity , so does the Sun. The Sun being a more massive object has greater acceleration (gravity). So as the Earth moves in a straight line, the Sun's gravity pulls is in to the Sun. However, these forces are all Balanced . so our forward speed is balanced by the Sun;s gravity, so we don't 'fall into the Sun' , but just go round/orbit the Sun.
What is a term for attraction or pull that every heavenly body has on or near it?
Gravity
What is a term the for attraction or pull that every heavenly body has on objects on or near it?
Gravity.
What is a term for the attraction or pull that every heavenly body has on objects on or near it?
Gravity.
What is the pull that bodies exert on one another?
Gravity.
How does gravitational pull of sun affect the heavenly bodies that revolve around it?
It keeps them in orbit around the sun.
When astronauts travel to the moon their bodies experience a lower gravitational pull than on Earth Which type of pull are they experiencing?
Which type of pull? This is still gravity, but now it's the Moon's gravity or "Lunar gravity".
Do the sun move?
Yes, The Sun Is always moving due to gravitational pull from heavenly bodies in the solar system.
Why aren't the planets in different shapes?
The planets mass creates gravity which pulls it into a spherical shape. This is the difference between planets and other heavenly bodies such as moons and asteroids. To be defined as a planet, a body must have enough gravity to pull itself into a spherical shape and it's gravity must be sufficient to clear its area of other debris.
What is the weigt of the sun?
Weight is a measurement of how heavy things are under the pull of gravity. You and I have weight, and so does air, trees, dirt, and so on. The Sun is not under a noticable pull of gravity, so we say it has "Mass". Mass is the same as weight on Earth, for instance, but not for other heavenly bodies. The Sun's mass is 1.98855±0.00025)×1030 kilograms, or equal to about 333,060 Earths.
Does gravity depend on density?
Gravity does not depend on density. Gravity is the gravitational pull that is invisible and cannot be touched or changed. Density is how much matter is packed within an object, which can be changed. Gravity and density are two totally different things, and are in no way related, therefore gravity does not depend on density.
How does gravity function as a pull or push?
A pull. Gravity is always attractive, so in the long run, gravity is the deciding factor in the motions of planetary bodies
