free-falling velocity

• Free-fall — is motion with no acceleration other than that provided by gravity. Since this definition does not specify velocity, it also applies to objects initially moving upward. Although the definition specifically excludes all other forces such as… …   Wikipedia

• Falling (physics) — Falling is descent under gravity. All objects have mass and in the presence of sufficiently massive objects such as planets or moons they experience a strong attraction due to gravity. This is known as weight. If the force of gravity is not… …   Wikipedia

• Terminal velocity — A free falling object achieves its terminal velocity when the downward force of gravity ( Fg )equals the upward force of drag ( Fd ). This causes the net force on the object to be zero, resulting in an acceleration of zero. Mathematically an… …   Wikipedia

• Equations for a falling body — Under normal earth bound conditions, when objects move owing to a constant gravitational force a set of dynamical equations describe the resultant trajectories. For example, Newton s law of universal gravitation simplifies to F = mg , where m is… …   Wikipedia
