How to Build a Flying Saucer II

Image

(Wikipedia is in my favor :lol: ...)

A somewhat counterintuitive aspect of the escape velocity is that it is independent of direction, then "speed" is a misnomer; is a scalar quantity and would be better described as "quickness to escape" or "scalar escape velocity". The simplest way to derive the formula for escape velocity is to use energy conservation as well: to escape, an object must have at least as much kinetic energy as the increase in potential energy resulting from moving to an infinite height .

Where there is gravity?

There are acceleration of a material point when there is a change in velocity of the same, within known temporal and spatial scales. Newtonian gravity is not an exception.

When here on earth, an elevator that is at the highest point of a building has cut its steel cable, everything inside the cabin loses its weight. For everything lose your weight, is need to down approach the Earth radius a relatively rectilinear motion, whose acceleration is 9.8 m / s ^ 2.

If this experiment is done with a rocket into outer space, where there is no gravity, so rocket launch an accelerated movement of 9.8 m / s ^ 2 in either direction, everything is inside the ship, will carry weight as if you were on Earth.

In the first case, the acceleration of the elevator cancels gravity, in the second case, the rocket acceleration produces gravity. This is a contradiction?

No, it isn't. In the case of the falling elevator, gravity is acting upon the elevator and the occupants with neither needing to be in contact with the other. In the case of the rocket, the motor's thrust is only acting on the rocket. If the motor's thrust could also act simultaneously on the occupants without needing to make contact, the result would be indiscernible from the falling elevator.

Matthew,
Thanks for your excellent explanation.
Indeed, the principle of equivalence, for example rocket versus lift, is valid only if gravity is an effect of thrust.

The problem of the equivalence principle in the inclined plane.

A rocket rises with the acceleration of the Earth. On the floor of the spaceship there is an inclined plane.
A ball is thrown to climb the ramp at a speed of 58.80 m / s.

At the end of the ramp, the ball will stop.

figure:

Schematic of the inclined plane inside the spaceship and apparent movement of the ball.

"Real" trajectory of the ball.

Well,
Imagine now that a trolley climbs the ramp at the speed of the ball
the previous example. On the trolley there is a pulley at rest:

If the equivalence principle is true, the pulley cart
moving should rotate 90 degrees to a complete stop the cart.


Practical test on the earth

A bicycle inside a subway car. The front wheel must be 100% balanced.

Build a tunnel inside the toroid.

Push a gas to circulate inside the toroid at a speed of 11,000 km / s or more.

Place the toroid on the surface of the Earth.

All points of toroid base must sit at same distance from Earth's center.

According to Newton's ballistics, the toroid will floats.
