Mass on a plane with friction
... If mass 1 is smaller than mass 2, mass 1 will accelerate upwards and mass 2 will accelerate downwards. Again assuming a massless non-stretching rope, we can say that these accelerations will be equal. Sum up the forces acting on mass 1: Σ F1 = T – m1g = m1a Note that this acceleration is positive be ...

Chapter 7 Motion
... • A powerful locomotive begins to pull a long line of boxcars that were sitting at rest. Since the boxcars are so massive, they have a great deal of inertia and it takes a large force to change their motion. Once they are moving, it takes a large force to stop them. • On your way to school, a bug fl ...

Vectors: Motion and Forces in Two Dimensions
... • Any vector - whether it is a force vector, displacement vector, velocity vector, etc. - directed at an angle can be thought of as being composed of two perpendicular components. These two components can be represented as legs of a right triangle formed by projecting the vector onto the x- and y-ax ...

I. Newton`s Laws of Motion
... This shows that no matter the mass, or weight of the object, the acceleration is always the same for all objects. The first part (left side) is 100 kg and the second part (10kg) is 10 kg but they still accelerate at the same rate. This was calculated using the equation from Newton’s Second Law. ...
