What if you had an ideal electric car driving on flat ground with no friction losses (i.e. if you turn off the motor, it coasts forever.)
If you draw constant power from the batteries, is it impossible to maintain constant acceleration?
- p1mrx 12y agoOh right, that makes sense; constant acceleration implies constant force, and work is force*distance. As the meters tick by more rapidly, the motor performs the same work in less time, and thus the required power increases. Which means, "a reactionless drive is like a car in space" would be a nonsensical concept without a preferred reference frame.
