and m1 distance double m2 distance that`s why the acceleration proportion is 2:1
is that right ?
Doc Al said:I don't see anything wrong with your equations. Solve them to find a.
Doc Al said:Oops. It looks like the masses are in equilibrium if they are equal. Are you sure you have the masses correct? (Also, what book are you using?)
Newton's laws of motion are three fundamental laws that describe how objects move in response to forces. The first law states that an object will remain at rest or in uniform motion in a straight line unless acted upon by an external force. The second 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 third law states that for every action, there is an equal and opposite reaction.
Newton's laws can be observed in everyday situations. For example, the first law can be seen when a book remains at rest on a table until someone applies a force to move it. The second law is demonstrated when a car accelerates in response to the force of the engine. The third law is evident when a person pushes against a wall and feels a force pushing back in the opposite direction.
Sure, let's say you want to calculate the acceleration of a car given its mass and the net force acting on it. First, you would use the second law (F=ma) to solve for the acceleration. Then, you would plug in the known values for mass and force to find the acceleration. For example, if a car with a mass of 1000 kg experiences a net force of 500 N, its acceleration would be 0.5 m/s^2.
Newton's laws are interconnected and build upon each other. The first law provides the foundation for the second law by establishing the concept of inertia. The second law explains how forces cause objects to accelerate, while the third law explains how forces always come in pairs. Together, these laws provide a complete understanding of how objects move in response to forces.
While Newton's laws are applicable to many situations, they do have limitations. They are most accurate for objects moving at low speeds and in non-relativistic situations. They also do not account for factors such as air resistance and friction, which can affect the motion of objects. In these cases, more complex theories, such as Einstein's theory of relativity, may be needed to accurately describe the motion of objects.
