Why a rocket moves upward
Follow the interaction between a rocket and its exhaust, and distinguish an action–reaction pair from forces on one object.
4-minute sample · No account neededWhat you’ll understand
- The rocket pushes exhaust gas downward; the gas pushes the rocket upward.
- Action and reaction forces act on different objects.
- Upward acceleration requires an upward resultant force on the rocket.
