Question

when combustion reactions occur inside a rockets engine, a lot of heat and pressure are released. the pressure gradient is much larger inside the rocket than outside, which causes the gaseous products to rush out of the rocket.
what does this create?
a. specific impulse
b. drag
c. thrust
d. fuel efficiency

Explanation:

The expulsion of high-pressure gaseous products from a rocket engine, driven by the internal-external pressure gradient and combustion heat, creates a reactive force that propels the rocket forward. This reactive force is defined as thrust.

Answer:

C. Thrust
