I wonder why you didn't use the template that is provided when you make a new post... anyway, what did you come up with?
What does your free body diagram look like? Which forces are acting on the block, in what directions and possibly magnitudes?
Newton's Laws of Motion are three physical laws that describe the relationship between an object's motion and the forces acting upon it. These laws were developed by Sir Isaac Newton and are fundamental principles in the study of physics.
Newton's Laws apply to a rocket in the same way they apply to any other object. The first law states that an object will remain at rest or in motion at a constant velocity unless acted upon by an external force. In a rocket, this means that the rocket will stay still or continue traveling at a constant speed unless a force, such as the thrust from the engines, is applied.
The first law of motion on a rocket is that the rocket will remain at rest or in motion at a constant velocity unless acted upon by an external force. This means that a rocket will stay on the launchpad until the engines are ignited, and it will continue traveling at a constant speed unless additional forces, such as gravity or air resistance, act upon it.
Newton's Second Law states that the acceleration of an object is directly proportional to the net force acting on the object and inversely proportional to its mass. In the case of a rocket, this means that the more force (thrust) applied to the rocket, the greater its acceleration will be. However, as the rocket's mass decreases due to fuel consumption, its acceleration will increase.
The Third Law of Motion states that for every action, there is an equal and opposite reaction. This means that as the rocket's engines exert a force to propel it forward, there is an equal and opposite force pushing back on the engines, causing the rocket to move in the opposite direction. This is why rockets have a large exhaust of gases shooting out of the bottom during liftoff.
