What is free fall?? In terms of physics
Answers
Free fall is the vertically downward motion of an object under gravity ignoring the air resistance acting on the body.
Ex : the motion experienced by a ball when released from the top of the tower
Answer:
Definition: When a body falls freely under the influence of gravity, then the body is to be in free fall.
Explanation:
In Newtonian physics, free fall is defined as the motion of an object where gravity is the only force acting upon it. By this definition then, a skydiver is never in true free fall, even before they deploy their parachute.
Free-fall, in mechanics, state of a body that moves freely in any manner in the presence of gravity. The planets, for example, are in free-fall in the gravitational field of the Sun. Newton’s laws show that a body in free-fall follows an orbit such that the sum of the gravitational and inertial forces equals zero. This explains why an astronaut in a spacecraft orbiting the Earth experiences a condition of weightlessness: the Earth’s gravitational pull is equal and opposite to the inertial—in this case, centrifugal—force because of the motion of the vehicle. Gravitational forces are never uniform, and therefore only the centre of mass is in free-fall. All other points of a body are subject to tidal forces because they move in a slightly different gravitational field. The Earth is in free-fall, but the pull of the Moon is not the same at the Earth’s surface as at its centre; the rise and fall of ocean tides occur because the oceans are not in perfect free-fall.
