It can cause an object to stop when a force is no longer applied. Four Forces of Nature The familiar force of gravity pulls you down into your seat, toward the Earth's center. You feel it as your weight. Why don't you fall through your seat? Well, another force, ...
What Pulls Us to EarthTayler, KathleenVisions International
Centripetal and centrifugal forces are two terms used to describe the physics of circular motion — but only one of them is real. The centripetal force keeps an object moving in a circle and is always pointed toward the center of that circle. For instance, the gravitational force of the sun...

Rain falls from clouds for the same reason anything falls to Earth.The Earth's gravity pulls it.But every cloud is made of water droplets or ice crystal(冰晶).Why doesn't rain or snow fall constantly from all clouds?The droplets or ice crystals in clouds are extremely small.The effect ...
23K In physics, gravity refers to the force that pulls anything with mass towards the Earth. Use this physics lab to explore acceleration and its relationship with gravity. Follow the physics lab steps, and do a data analysis to understand how gravity affects acceleration. Related...
The gravitational force tugging between two bodies depends on how massive each one is and how far apart the two lie, according toNASA Glenn Research Center. Even as the center of theEarthis pulling you toward it (keeping you firmly lodged on the ground), your center of mass is pulling bac...
