How Our Rockets Will Work: Newton’s Third Law of Motion
Newton’s third law says that for every action (force) there is an equal and opposite reaction (force).
SIMPLY: If you push an object, that object pushes back in the opposite direction equally hard.
Forces are found in pairs. Think about every time you sit in a chair. Your body exerts a force downward and that chair needs to exert an equal force upward or the chair will collapse. It’s an issue of symmetry. Acting forces encounter other forces in the opposite direction. There’s also the example of shooting a cannonball. When the cannonball is fired through the air (by the explosion), the cannon is pushed backward. The force pushing the ball out was equal to the force pushing the cannon back, but the effect on the cannon is less noticeable because it has a much larger mass.
