Rocket works principal of conversion of?

Question

1. mass
2. energy
3. angular momentum
4. linear momentum

Answer 1

Linear momentum. But it's "conservation" of linear momentum, not "conversion". The rocket starts with zero momentum, chucks a lot of mass out backwards, so to conserve zero momentum has to accelerate forwards.

Answer 2

4

Answer 3

4

Answer 4

A rocket converts the chemical potential energy of the fuel into linear momentum.

Answer 5

Newton's Third Law Of Motion i.e angular and linear momentum

Answer 6

Actually we conserve the linear momentum for deriving the formulae of rocket propulsion.

but one cant say that mass is not conserved here.

hence both 1&4

Answer 7

energy and linear momentum

its 1 and 4

Answer 8

First, there absolutely IS gravity in space. The earth's gravity extends well beyond the moon; the sun's gravity extends well beyond Pluto. Astronauts in space feel a sense of weightlessness because gravity is pulling both the astronaut and the spacecraft along the same path. As the astronaut falls, so does the spacecraft, so an astronaut can "float" next to the wall of the spacecraft instead of being pulled into it. Space ships make use of gravity to adjust their paths. The also use rocket engines, whose primary purpose is to expel matter away at high speeds. Whenever you push something away from yourself, there is a "recoil" action that pushes you in the opposite direction. Rocket engines shoot matter in one direction, and the spacecraft recoils in the opposite direction.

Answer 9

Translates potential energy (from fuel) into kinetic energy (gases). Reaction to gas expulsion propels rocket.

Answer 10

linear momentum
