That all makes sense, but the confusing part is that the engine uses energy to exert a force that changes the velocity.
If the engine consumes a constant amount of energy and exerts a constant force, it produces a linear acceleration.
In other words, Daox was not wrong in stating that it takes the same amount of energy to accelerate from 10-20 MPH, as it does to go from 40-50 MPH.
How does a constant chemical energy conversion into kinetic energy result in exponentially growing kinetic energy?
