Your weight changes on other planets and moons due to different gravitational pulls. Weight is how much gravity pulls on you; mass (amount of matter) stays the same. Newton's Law of Gravitation ...

All of the objects in our solar system are acted upon by forces. Forces are pushes or pulls. Every force has both a strength and a direction. Applying a force on something–like pushing a toy car–can ...

Even teeny objects obey the law of gravity. A gold ball just 2 millimeters wide, with a mass of about 90 milligrams, is now the smallest object to have its gravitational pull measured. Observations of ...
