Path of any projectile in absolute vaccum?
Sep 27, 2021
The entire universe, even the Multi-Verses are in the pool of gravity. The motion of any celestial body in these systems is affected by gravity of any other larger body. Let us assume that there is an absolute vaccum i.e the space of no gravity, no internal or external forces at all. My question is, in that absolute vaccum, what will be the path of any projectile thrown with some velocity? People may say that it is straight according to Newton's Law. When we think of the distances of quadrillions of light years, will this straight be straight only or will its meaning change?

Is linear addition of velocities of different rockets in a system of rockets, possible ?
Sep 17, 2019
Let there. is a system of rockets having the rockets R1, R2, R3, . . . . . . . Rn with firing velocities of V1, V2 , . . . . . . .Vn respectively such that R 2 is on the top of R 1, R 3 is on the top of R 2 and so on. If all these rockets are fired with their respective velocities one after the other, starting from R 1, will the Vn = V 1 + V 2 + . . . . . . .V n ? If it is possible, then it is easy to design a system of rockets which will save the fuel, time and we can make incredible velocities of the space missions, possible. To save the payloads from jerking, the payloads may be housed in shock absorbing chamber in the rocket system.
