Is it wrong to assosciate relative frames of reference with Einstein? If Galileo invented the concept...

There's no m in the force of the falling component. It wouldn't the propel the cube. Can't move shit without mass bozo. YOU MAD CUZZA MY WORK

cwutididtherehoho

The force propelling the cube is its own inertia and the unmoving platform underneath it. The cube is squeezed through the rapidly descending portal, emerging at a velocity of h/T, meaning the cube has velocity.

Portals are nonconservitive in both angular and transnational momentum for objects that pass through them. Either the momentum is not conserved in the larger system or the portals must exert equal and opposite forces at both the entrance and exit portals.

I have a machine, an object enters the machine at one end, I record the object's orientation, rotational and transnational state. Then my machine grabs the object, transports it through an elon musk hyperloop to the ejector which imparts the same orientation and rotational and transnational momentum, but rotated to my desired exit angle.

Functionally my machine is identical to a portal except the object doesn't enter and exit simultaneously. My entrance must absorb the difference in momentum between the grabber and cube, either the grabber or cube could be moving. The exit must also conserve momentum as it accelerates the cube for ejection.

From the moving portal's reference frame the cube is moving and has momentum.

>meaning the cube has velocity.
Right, but the force moving it has no mass. Without force exerted upon something, there's 0 work done to the object, thus there's no distance. W = fd

>From the moving portal's reference frame the cube is moving and has momentum.

Tricky. You're right. I'll give it to ya, man. Thanks for clarifying

Actually, wait. If there's no work being done on the object, then it can't move. There's no acceleration, but only a velocity which stops once the descending platform hits the pedestal.

PLOP :D

ilu

The acceleration stops once the portal stops moving, no force = no distance.

why would the cube's velocity change? you need work for that to happen, and there's nothing acting upon it.

>nobody taking into account that gravity pulling it down in A is going against gravity keeping it on the platform

Sigh brainlets....

With zero velocity at the end of the portal's descension, the momentum of the block would also become 0.

what force is stopping the cube? is it the same one that's stopping the orange portal?

The cube only gains velocity congruent to the falling portal. Once the portal stops moving, the cube also does..
