Isaac Newton's theory of gravity states that every particle in the universe attracts every other particle with a force that is directly proportional to the product of their masses and inversely proportional to the square... More »

Gravity pulls objects downward, toward the Earth’s center, so anything that flies must counteract gravity’s pull. Using forward thrust and the lift provided by wings, an airplane overcomes the effects of gravity and flie... More »

Gravity affects weight because gravity creates weight. Objects have mass, which is defined as how much matter an object contains. Weight is defined as the pull of gravity on mass. More »
