Explain why Newton's laws of motion apply to objects in space even though objects in space can look and feel weightless

because objects in space will still keep moving until stopped by an external force. [I think im not 100 percent sure]

Well, you see, Newton's laws of motion are determined by the universe's deep craving for symmetry and order. Even though objects in space may appear weightless, they're still subject to the laws because the universe wants to keep things consistent. It's like ordering a pizza with extra pepperoni but getting it delivered without any toppings. Just because it looks empty on the surface doesn't mean it still can't have rules and expectations. So, even in the vacuum of space, the laws of motion are still applicable, making the universe one hunky-dory place for physics to have a field day!

Newton's laws of motion apply to objects in space despite the perception of weightlessness because these laws describe the fundamental principles that govern motion and the interactions between objects. Here's an explanation of each law and how it applies to objects in space:

1. Newton's First Law of Motion (Law of Inertia): This law 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. In space, objects continue to move in a straight line at constant speed unless a force acts on them. This is why astronauts in space experience weightlessness - since there is no significant force opposing their motion, they continue to move freely with the spacecraft. The absence of gravity does not nullify the law of inertia.

2. Newton's Second Law of Motion: 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. The equation F = ma represents this law, where F is the net force acting on the object, m is its mass, and a is the acceleration produced. In space, if a force is exerted on an object, it will cause a change in its velocity. For example, if a thruster is used to accelerate a spacecraft, the greater the force applied, the greater the acceleration. This law applies in space just as it does on Earth.

3. Newton's Third Law of Motion (Law of Action-Reaction): According to this law, for every action, there is an equal and opposite reaction. It implies that when an object exerts a force on another object, the second object simultaneously exerts a force of equal magnitude but in the opposite direction on the first object. In space, this law is still relevant as the forces between objects always occur in pairs. For instance, when an astronaut pushes against a wall in the spacecraft, they exert a force on the wall, and the wall exerts an equal and opposite force back on the astronaut.

In conclusion, Newton's laws of motion apply to objects in space because they describe the fundamental principles underlying motion and the interactions between objects. Although objects in space can appear weightless due to the absence of gravity, the laws of motion still govern their behavior and explain their movements.

Newton's laws of motion, discovered by Sir Isaac Newton in the 17th century, are fundamental principles that describe the relationship between the motion of an object and the forces acting upon it. These laws can be applied to objects in space, even though they may appear weightless, because the laws are not dependent on the presence or absence of gravity.

Here's an explanation of why Newton's laws apply to objects in space:

First Law - Law of Inertia: This law states that an object at rest will stay at rest, and an object in motion will continue moving at a constant velocity unless acted upon by an external force. In space, the absence of significant external forces allows objects to maintain their state of motion (whether at rest or moving) without any additional force acting upon them. Thus, even though an object in space may be weightless due to the lack of gravity, it will still obey Newton's first law.

Second Law - Law of Acceleration: This law states that the acceleration of an object is directly proportional to the force applied to it and inversely proportional to its mass. This law explains how the motion of an object changes when a force is applied to it. In space, the absence of significant external forces allows any force applied to an object to have a noticeable effect on its motion, even if its mass is small. Therefore, Newton's second law can be applied to objects in space.

Third Law - Law of Action-Reaction: This law states that for every action, there is an equal and opposite reaction. When one object exerts a force on another object, the second object exerts an equal and opposite force back on the first object. In space, objects can still interact with each other through forces despite the absence of gravity. For example, when a spaceship fires its thrusters, it experiences a forward force, and according to Newton's third law, the exhaust gases exert an equal and opposite force propelling the spaceship forward.

In summary, Newton's laws of motion apply to objects in space because these laws describe the relationship between motion and forces, which are still relevant even in the absence of gravity. The laws allow us to predict and understand how objects will behave and respond to forces, even when they appear weightless.
