Gravity is a force that attracts objects towards each other. It is responsible for the weight of an object and the sensation of being pulled towards the ground on Earth. The force of gravity is determined by the mass of the objects and the distance between them.
Air resistance, sometimes called drag, is a force that opposes the motion of an object as it moves through the air. It is caused by the air molecules colliding with the object, creating a frictional force that acts in the opposite direction of the object's motion. Air resistance depends on factors such as the speed and size of the object, as well as the density and viscosity of the air.
When an object is falling through the air, both gravity and air resistance affect its motion. At the beginning of the fall, the force of gravity is greater than the air resistance, causing the object to accelerate downwards. As the object gains speed, the force of air resistance also increases, eventually reaching a point where it balances the force of gravity. This is known as terminal velocity, which is the maximum speed an object can reach while falling.
The interaction between gravity and air resistance is important in many phenomena, such as skydiving, parachuting, and the flight of birds and aircraft. Understanding these forces is crucial in designing vehicles and equipment that can overcome or take advantage of them.
