"The Impulse" is a poem by Robert Frost that explores the idea of free will and the choices individuals make. It suggests that our actions are driven by an internal impulse, rather than external influences or circumstances. The poem emphasizes the importance of following one's instincts and inner desires.
A simple turbine.
Air is drawn into the engine continuously and compressed by a series of rotating blades. Fuel is sprayed into the combustion chamber and burnt increasing the gas temperature to around 1200C.
The hot high pressure gas expands through a second set of blades mounted on the same shaft as the compressor blades. The energy of the gas is partially expended powering the compressor, but has a residual energy which is either expended as a hot jet (resulting in thrust) or which drives a further independent set of blades to power a propeller or other device.

When lightning strikes the top of a tree and the lightning makes its way all the way to the ground, I would definitely say yes they do.
in the case of impule turbine total energy at inlet is kinetic energy and in case reaction turbine energy at inlet is kinetic and pressure......
I believe the answer is no. The impulse produced is also time related. Impulse force is measured as dp/dt. Therefore a smaller force produced for a very quick time could produce a larger impulse than a large force over a longer time.
