How does Newton's third Law relate to rocket movement?
Newton's third Law: ''To every action there is always an equal and opposite reaction: or the forces of two bodies on each other are always equal and are directed in opposite directions''. The force of a rocket's engine must be able to overcome the force of Earth's gravity applied to the rocket's mass. So, the engine must exert a force at least equal to the force of gravity and in the opposite direction of the force of gravity before any upward movement can occur.

Does the reactions force occurs before the action force?
Asked in Science
Do forces occur alone or in pairs?
According to Newton's three laws of motion: Whenever a first body exerts a force F on a second body, the second body exerts a force −F on the first body. F and −F are equal in magnitude and opposite in direction. This indicates that Forces occur in pairs. However these pairs do not act on the same object simultaneously, but on two separate objects.
