A force is a push or pull that acts upon an object as a result of that objects interactions with its surroundings. In this Lesson, The Physics Classroom differentiates between the various types of forces that an object could encounter. Some extra attention is given to the topic of friction and weight.

A catalog of forces will be useful for reference as we solve various problems involving force and motion. These forces include normal force, tension, friction, and spring force. Normal force. Weight (also called the force of gravity) is a pervasive force that acts at all times and must be counteracted to keep an object from falling.
Forces are given many names, such as push, pull, thrust, and weight. Traditionally, forces have been grouped into several categories and given names relating to their source, how they are transmitted, or their effects. Several of these categories are discussed in this section, together with some interesting applications.
13 sty 2024 · When an object rests on an incline that makes an angle \(\theta\) with the horizontal, the force of gravity acting on the object is divided into two components: a force acting perpendicular to the plane, wy , and a force acting parallel to the plane, wx (Figure \(\PageIndex{3}\)).
There are four fundamental forces in nature - gravitational, elctromagnetic, weak-nuclear, and strong-nuclear forces. But, in everyday life, we encounter many effective forces that have their origins in gravitational and elctromagnetic forces.
Define the SI unit of force, the newton. Describe force as a vector. The study of motion is called kinematics, but kinematics only describes the way objects move—their velocity and their acceleration. Dynamics is the study of how forces affect the motion of objects and systems.
About 20 different forces are briefly described. The use of free body diagrams is explained. Newton's 1st law of motion is stated and used to define force.
