._|evo|_. said:Like how you can apply them to stuff. I just need someone to recap in simple words, I'm not really good at big fat definitions.
I'm also asking cause my teacher keeps on emphasizing that Newton's laws 1 & 3 are pretty much useless, and only 2 is important.
Whitishcube said:his first law describes inertia, that a body in motion stays in motion unless acted on by another force. that's a pretty important concept. it explains why planets basically orbit each other and TONS of other important things. not quite useless in my book.
Newton's Laws of Motion are three fundamental principles of physics that describe how objects move and interact with each other. They were developed by Sir Isaac Newton in the 17th century and are considered the foundation of classical mechanics.
The First Law of Motion, also known as the Law of Inertia, states that an object at rest will remain at rest and an object in motion will remain in motion at a constant velocity, unless acted upon by an external force.
The Second Law of Motion 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 other words, the greater the force applied to an object, the greater its acceleration will be, and the more massive an object is, the less it will accelerate under the same force.
The Third Law of Motion, also known as the Law of Action and Reaction, 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 will exert an equal and opposite force back on the first object.
Newton's Laws of Motion provide a framework for understanding and predicting the movement of objects in the world. They help explain why objects move in certain ways and how forces interact to cause changes in an object's motion. These laws have been tested and proven through numerous experiments and are used in various fields, including engineering, astronomy, and sports.
