What is Acceleration Due To Gravity?
Acceleration due to gravity is the rate at which an object falls towards the center of the Earth due to its gravitational pull. This concept is important for understanding how objects move and interact in our universe, as well as how forces like friction and air resistance affect their motion. The acceleration due to gravity is a constant value, which means that all objects experience the same force regardless of their size or mass. On Earth, the acceleration due to gravity is 9.8 m/s2 (32 ft/s2).The acceleration due to gravity affects all objects on Earth. When an object falls freely with no other external forces acting on it, it accelerates at a rate of 9.8 m/s2 (32 ft/s2). This means that after one second, the object will have fallen 16 feet (4.9 meters). After two seconds, it will have fallen 32 feet (9.8 meters), and so on until it reaches terminal velocity where air resistance counteracts gravity’s pull and keeps its speed from increasing further or until it hits something else solid like the ground or another object in its path.The acceleration due to gravity also affects other aspects of motion such as projectile motion and circular motion; for example, when a ball is thrown upward at an angle, its trajectory follows a parabolic path because of gravitational acceleration pulling it back down towards Earth’s surface again after reaching its apex point in midair. Similarly, when an object moves in a circle such as when riding on a merry-go-round or swinging from a rope swing around an axis point like Earth’s center of mass, then this same gravitational force acts upon it causing centripetal acceleration which keeps the object moving in circles instead of having linear momentum away from that axis point into outer space.In conclusion, Acceleration Due To Gravity is essential for understanding many aspects of movement throughout our universe and has been studied by scientists since antiquity.
