Gravity is based on an object's mass and your distance from the center. When you're on the surface of a planet, you can use the planet's radius to calculate your distance from the center. If you compare the mass of the moon to the earth's, you will find that the moon's mass is...
Astronomers (professional or amateur) can measure a star's brightness (the amount of light it puts out) by using a photometer or charge-coupled device on the end of a telescope. If they know the star's brightness and the distance to the star, they can calculate its luminosity — the am...
Draw a diagram of various forces acting on a 5-kilogram block falling through space. Suppose it has gravity pulling down vertically on it, another force pulling it left with a force of 10 Newton (the SI unit of force), and another force pulling it up and to the right at an angle of ...
To weigh the Earth, we would need to know in which object's gravitational field we want to calculate the weight. The mass of the Earth, on the other hand, is a constant. Mass of Earth FAQs How is Earth mass calculated? Since scientists already know the radius of planet Earth, they us...
On February 8, 2022, approximately 40 of the 49 Starlink satellites were reported to have lost altitude, leading to atmospheric re-entry. SpaceX reported that the orbital decay on Starlink satellites was considered to be linked to a geomagnetic storm that was initiated on February 3, 2022. We...

You won't be moving quite as fast at other latitudes, however. If we move halfway up the globe to 45 degrees in latitude (either north or south), you calculate the speed by using the cosine (a trigonometric function) of the latitude. A good scientific calculator should have a cosine fu...
Calculate the gravitational strength of Pluto. How are dwarf planets different from terrestrial planets? What keeps the planets in orbit? What is the gravity on Ceres? How was Jupiter discovered? How to find the orbital distance of a planet What spacecraft used the gravitational pull of the...
We know, from Newton's Laws of Motion, that all motion is linear, unless an outside force acts upon an object. On the Earth, this centripetal force is generally applied through contact forces.Answer and Explanation: The force of gravity that exists between the planets and the sun provides ...
