The Lee-Tseung Lead Out Theory

[Cap-Z-ro]

An ounce of prevention...

Certainly, an object cushioned against a fall is less likely to sustain damage.  However, this has nothing to do with the propulsion system you propose.  The energy absorbed by the ground is the same, whether I fall on a pillow or land on my feet.

You never answered my hopothetical.  Do you believe the harder object, the baseball, will retain some of its forward motion after the collision with the soft foam ball (of equal mass)?  The objects are travelling at equal speeds toward each other in gravity-free space.

shruggedatlas, glad to hear your cry for help again.

First the force hitting the ground with an iron plate and an air cushion are definitely different.  This is because the rate of change of momentum in the two cases are different.

Second the energy received by the ground will be different.  Some energy will dissipate as sound; some as deformation, some as breaking of bones, some as blood splashing to mid-air, etc.

Change your two-ball scenario a little bit.  Instead of pointing them at each other, direct them to two opposite sides of the silly spaceship by Tseung.  You will get two different forces acting on the two sides of the spaceship.  This will result in moving the spaceship in the direction of greater force.  Use your trained brain more.  It is a pity that you did not have a physics degree.  If you had undergone a few years vigorous training, you might even be able design a Flying Sauce and ride on it to visit me.

No, it's a pity that even with your physics degree, you cannot grasp these elementary things.  You still have not answered my question, and you are not going to, because it can be tested, and you cannot stand to be proven wrong.

I was just thinking of cosmic engines.

What if we where to point a compass needle as straight as we can at a planet some place in our solar system. We keep the needle aimed at the planet for years. Wouldn't the planet express force onto the needle depending on how accurate we can match it's speed?

What if we aim a huge mass slightly below the speed of that planet?

Wouldn't it start dragging it along?

Gaby,

If we can shield one end of the magnet so that the main effect on it from the distant planet with magnetic pole is attracton, you can get the magnet moving towards the planet.

We assume that there is no other force acting on the magnet to pull it in other directions.

If we do not shield the magnet, there will be the repulsion from the other pole of the magnet.

The question will be similar to pure gravitational attraction.
