Learn how to use force diagrams to analyze the forces and torques acting on a rigid system. Explore how force and torque can lead to rolling in different situations.

The motion of objects is determined by the relative size and the direction of the forces that act upon it. Free-body diagrams showing these forces, their direction, and their relative magnitude …

Like displacements, velocities, and accelerations, forces are vectors that have magnitude and direction. We may represent a force as the sum of two vectors at right angles. These are its …

Key Points Multiple forces act on an object at the same time. The size and direction of these forces determines the movement of the object.

Motion diagrams are a series of visual representations (dots, arrows, or both) that depict an object’s position at regular intervals of time. Motion diagrams provide a snapshot of how an …

A force diagram, also known as a free-body diagram, is a visual representation of the forces acting on an object or system. It is a crucial tool in the analysis of Newton's Second Law of …

Identifying the forces and drawing them into a free-body diagram is the critical first step in solving almost any problem using Newton’s Three Laws of Motion.

Air resistance acts against an object moving through air. The free-body diagram (FBD) of an object shows all the forces acting on that object. It is an indispensable tool in helping to solve …

Master Types Of Forces & Free Body Diagrams with free video lessons, step-by-step explanations, practice problems, examples, and FAQs. Learn from expert tutors and get exam …

In a force diagram, balanced forces have arrows of equal length pointing in opposite directions, showing no change in motion. Unbalanced forces have arrows of different lengths or more …
