Give an example of something that uses all third of Newton's Law.

An example that involves all three of Newton's Laws of Motion is a person launching a rocket into space. Let's break down how each law is applied in this scenario:

1. Newton's First Law: Also known as the law of inertia, it states that an object at rest will remain at rest, and an object in motion will continue moving in a straight line with a constant velocity unless acted upon by an external force. In the case of a rocket launch, the rocket itself is initially at rest, and according to Newton's First Law, it would remain at rest without any external force acting on it. To overcome this, the rocket engines ignite, generating a force that propels the rocket forward.

2. Newton's Second Law: This law states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. It can be expressed as the equation F = ma, where F is the force, m is the mass of the object, and a is the acceleration. In the case of the rocket launch, the ignited rocket engines generate a force (F) pushing the rocket. Since the force applied to the rocket is greater than the external forces like gravity, friction, and air resistance, the acceleration (a) of the rocket increases. This acceleration allows the rocket to overcome gravity and gain altitude. Additionally, the mass (m) of the rocket is taken into account in this equation. As the fuel burns and is expelled from the rocket, its mass decreases, which in turn affects the acceleration.

3. Newton's Third Law: This law states that for every action, there is an equal and opposite reaction. When the rocket engines expel high-speed gases or exhaust, the gases exert a force pushing in the opposite direction. According to Newton's Third Law, the expelled gases exert an equal and opposite force that propels the rocket forward. This principle is referred to as "action-reaction," where the action is the expulsion of gases from the engine, and the reaction is the forward motion of the rocket.

In summary, launching a rocket into space involves all three of Newton's Laws of Motion. The first law is applied to overcome the initial inertia, the second law explains the acceleration of the rocket, and the third law demonstrates the action-reaction forces between the expelled gases and the rocket.
