Why is free fall acceleration?

Freefall is a special case of motion with constant acceleration, because acceleration due to gravity is always constant and downward. This is true even when an object is thrown upward or has zero velocity. Near the surface of the earth, the change of acceleration due to gravity is negligible.Click to see full answer. Considering this, why is free fall important? Free Fall Motion Objects that are said to be undergoing free fall, are not encountering a significant force of air resistance; they are falling under the sole influence of gravity. Under such conditions, all objects will fall with the same rate of acceleration, regardless of their mass.Additionally, what is meant by free fall motion? In Newtonian physics, free fall is any motion of a body where gravity is the only force acting upon it. In the context of general relativity, where gravitation is reduced to a space-time curvature, a body in free fall has no force acting on it. Similarly, it is asked, why is free fall acceleration near Earth’s surface? Explain why free-fall acceleration near Earth’s surface is constant. Near Earth’s surface, the distance between the object that is falling and the center of Earth does not change very much. The extra mass of the heavy object exactly compensates fot the additional gravitational force.Is acceleration constant in free fall?An object that is moving only because of the action of gravity is said to be free falling and its motion is described by Newton’s second law of motion. The acceleration is constant and equal to the gravitational acceleration g which is 9.8 meters per square second at sea level on the Earth.
