then how does terminal velocity come into play?
to be strictly speaking, something can keep on accelerating as long as an increasing force is applied right>?
Can something keep on accelerating?if d^2x/dt^2 can be regarded as acceleration, then what is d^3x/dt^3?
if not? why not?
constant acceleration = circular motion resolves it to be a infinite change of direction, however it does not answer the idea of magnitude.
