The acceleration formula is one of the basic equations in physics, something you’ll want to make sure you study and practice. These are all quadratic equations in disguise: It means the act of ejecting molecules pushes back on the rocket: every time a water molecule flies from the nozzle, the rocket loses a little mass and in return gains a little velocity. If the same acceleration and time are used in the equation, the distance covered would be much greater. If the dragster were given an initial velocity, this would add another term to the distance equation. A rocket with a little less Î v {\displaystyle \Delta v} can accomplish this goal, but it is less forgiving of less efficient piloting. Acceleration is a measure of how much the speed increases each second. These are all quadratic equations in disguise: Quadratic Equation Solver.

Mathematically, work can be expressed by the following equation. In addition to being useful in problem solving, the equation v = v 0 + a t v = v 0 + a t gives us insight into the relationships among velocity, acceleration, and time. Is it Quadratic? In order for the left side of our equation to remain in balance with the right side, acceleration of the rocket has to increase as its mass decreases. Thus the rocket's mass smaller during flight.
