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 »

Mass has a direct effect on gravity, while weight is simply a measurement of the force of gravity on an object. While an object's mass stays the same no matter where it is located, the more mass an object has, the greate... 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 »

Objects fall at the same velocity regardless of their weight, if gravity is the only force acting upon them. In a vacuum, where air resistance has been eliminated, a bowling ball and a feather fall at the same speed. More »

Altitude affects air pressure due to gravity. Gravity causes the pressure to increase or decrease based on the air's distance from sea level. Pressure decreases at higher altitudes. More »
