Question

Ma/ma = Mg-T/T-mg.
find the equation for tension (T) of connected motion ​

Answer 1

Now that we know Newton's Laws of Motion, how do we apply them? How can they let us predict the motion of an object if we know all the forces acting upon it? How can they let us predict the forces on an object if we know its motion?

It is only a slight over statement to say that the rest of this course is just looking for devious ways to apply

F = m a
