Description of Freefall - "When buoyancy and air resistance can be neglected, a falling body has the constant acceleration
and the formulas for uniformly accelerated motion apply to it." Beiser Pg. 11
History of FREEFALL
Aristotle was first scientist to understand the fact that objects that weigh more or have greater density, fall faster than objects that weigh less or have less density. During the 16th century, Galileo found the formula for the speed that increases as an object falls freely to the ground. Sir Isaac Newton's second law of motion states that the net force acting on a body is proportional to the mass of the body and to its acceleration. Then Einstein developed the Theory of Gravitation, Now we know that when we drop a rock or a tissue from the same height, the rock will reach the ground faster than the tissue. However, if the tissue is compressed it will reach the ground faster.
- FREEFALL helped with the development of the space program and space exploration.
