Because magnets arent real, or 3rd Newton Law

>> No.9976610

>>9976585
Since neither magnet is fixed to anything, they don't know which one is supposed to move and which is supposed to be stationary, so they just do nothing. This is called the uncertainty principle.

A similar problem to the first; because the blades exert a similar force down on the cockpit as to the air, you don't actually move. Not to mention that, were you somehow able to counteract that force, the force of the air above the cockpit rushing down to meet the vacuum would slam it right into the ground.

pic related, however, is a real head stratcher.

If you were to push the chair with an inhuman amount of force, you would negate your downward velocity and be okay, but that amount of energy is unpossible to unleash using your human legs.

It could work, if you trained your legs hard enough I think, but the problem is you'd have to jump hard enough to decelerate you that it's comparable to hitting the ground in the first place. Instead of the landing killing you, the jump would.

No, it's just two magnets. Try to put compass on top of magnet and observe whether it keeps spinning or if it stops after finding some equilibrium.

the chair would also have to have enough mass that the power from your legs would be able to displace you from the chair rather than simply accelerating the chair downwards so say for instance if the chair was made of depleted uranium and instead of using your legs you was to put a car airbag on the seat rigged to detonate 1 m from the ground it might slow you to a more survivable 10 m per second descent which using an emergency parachute landing technique in other words collapse and roll it could be very feasible to do. in lieu of having a depleted uranium share something larger for example a large safe would do a similar job and do it even better because of the extra wind resistance drag factor would mean you and the safe are falling slower to start with

You increase the strength of the magnet attached to the pole, meaning the force being pulled toward the pole magnet is stronger than the magnet attached to the car, creating a net forward force, pulling the car forward.
