?What is Newton's First Law of Motion, and how does it relate to the concept of inertia

Newton's First Law of Motion states that an object at rest tends to stay at rest, and an object in motion tends to stay in motion with the same speed and direction unless acted upon by an external force. This law is often summarized as "an object in motion stays in motion, and an object at rest stays at rest." It is closely related to the concept of inertia, which is an object's resistance to change in its state of motion. Inertia is directly proportional to an object's mass, meaning that objects with greater mass have more inertia.

?ird Law of Motion state, and can you provide an example

Newton's Third Law of Motion states that "for every action, there is an equal and opposite reaction." This means that when one object exerts a force on another object, the second object exerts an equal force in the opposite direction. For example, if you push a wall, the wall pushes back with an equal force. In rocket propulsion, hot gases are expelled out of the back of a rocket, creating a forward thrust force due to the equal and opposite reaction, which propels the rocket forward in space. This law demonstrates the conservation of momentum in closed systems.
