Forces in 2D

The Adding and Resolving Forces Video Tutorial reviews the two critical operations associated with force vectors - addition and resolution. The importance of vector addition of forces and of vector components is explained.

The Net Force Problems Revisited Video Tutorial discusses a logical strategy for approaching an analysis of a situation in which a force is applied to an object at an angle to the horizontal in order to accelerate it across a level surface.

The Equilibrium Video Tutorial explains what is meant by the term "equilibrium" and shows how to conduct a mathematical analysis of the force vectors to determine if an object is at equilibrium.

The Inclined Planes Video Tutorial discusses the physics of objects moving along inclined planes. The identification of the forces, the drawing of a free-body diagram, the components of gravity, and the application of Newton's second law to the analysis are discussed in an organized and understandable manner.

The Modified Atwood's Machines Video Tutorial discusses the use of a system analysis and an individual object analysis in the solving of problems associated with Modified Atwood's Machines. After a thorough discussion of the strategy, two example problems are done.
