Question

Newton’s Laws of Motion are absolute in classical physics. One example that uses all three laws simultaneously is the firing of a rocket in space. Hollywood uses this idea when they use fire extinguishers, or a rocket, in space to move about. Write a brief essay describing how Newton’s Laws explain how a rocket in space can move objects. Be sure to touch on each law within your essay.

Answer 1

1) Inertia keeps the object moving in a uniform motion
2) The force applied by a fire extinguisher or such applies a force on the user that is proportional to the mass of the system multiplied by the acceleration of the system
3)the user will be propelled in an exact opposite direction from the blast of the fire extinguisher
