Key Concepts

Decomposition of Forces

Decomposing forces involves breaking a force into components along mutually perpendicular axes, such as parallel and perpendicular to a surface. This method simplifies the analysis of forces, especially on inclined planes, by allowing the separate treatment of forces acting in different directions.

Free-body Diagram

A free-body diagram is a simplified representation of an object where all the forces acting upon it are depicted as vectors. This tool helps in identifying and visualizing forces such as gravitational, normal, frictional, and any applied forces, which is essential in solving problems involving equilibrium or motion.

Normal Force

The normal force is the support force exerted by a surface perpendicular to the object in contact with it. It arises as a reaction to the object's weight or any perpendicular component of applied forces, and is crucial for analyzing dynamics on inclined or curved surfaces.

Newton's Laws of Motion

Newton's laws, especially the first and second laws, form the basis for understanding the balance of forces. In cases where an object is in equilibrium or moving at constant velocity, the net force in each direction is zero, enabling the calculation of forces like the normal force through proper decomposition and summing of forces.
