[1] [2] ROCKETS Educator’s Guide with Activities in Science, Technology, Engineering and Mathematics by NASA’s Newton’s Laws of Motion In simple language, Newton’s Laws of Motion: Newton’s First Law This law simply points out that an object at rest, such as a rocket on a launch pad, needs the exertion of an unbalanced force to cause it to lift off. The amount of the thrust (force) produced by the rocket engines has to be greater than the force of gravity holding it down. As long as the thrust of the engines continues, the rocket accelerates. When the rocket runs out of propellant, the forces become unbalanced again. This time, gravity takes over and causes the rocket to fall back to Earth. Following its “landing,” the rocket is at rest again, and the forces are in balance. There is one very interesting part of this law that has enormous implications for spaceflight. When a rocket reaches
