The phrasing in the book is just dumb, that's all there is to it.th77 said:You're right because I got the answer using it, but I don't know why. The problem says that only 2 'horizontal' forces act on the object. Why is the vertical involved? I know F2 is making an angle, but then what do they mean by horizontal forces? Shouldn't it just say 'forces'? I have a sample problem in the book that specifies there is one-dimensional motion yet 1 of the forces is making an angle.
Newton's Second Law states that the acceleration of an object is directly proportional to the net force acting on the object and inversely proportional to its mass.
Newton's Second Law can help explain why an object may not be behaving as expected. If the acceleration is not what was predicted, it could be due to an incorrect application of force or an incorrect measurement of mass.
Some common mistakes include not taking into account all of the forces acting on the object, not properly calculating the net force, and not considering the mass of the object.
To correctly apply Newton's Second Law, it is important to identify and consider all of the forces acting on the object, properly calculate the net force, and accurately measure the mass of the object.
You can check your calculations and measurements to ensure that the acceleration you have calculated matches the actual acceleration of the object. If they do not match, it may indicate an error in your application of Newton's Second Law.
