Image of jet plane showing the four forces: Lift - upwards, Weight - downwards, Thrust - forwards, and Drag - backwards.
Newton's Second Law with mass constant: F equals m a
F equals Force equals Lift minus weight or thrust minus drag.
a equals F divided by m.
If force remains constant, accelerations is constant:
V equals a t plus V subzero
X equals a T-squared over two plus V subzero T plus X subzero
