    Dec 4, 2025 · force, in mechanics, any action that tends to maintain or alter the motion of a body or to distort it. The concept of force is commonly explained in terms of Isaac Newton ’s three laws of …

  3. Types of Forces - The Physics Classroom

    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.

  4. Forces in Physics: Definition, Types, and Examples

    In physics, a force is defined as any influence that causes an object to undergo a change in motion. Mathematically, force is a vector quantity characterized by both magnitude and direction. For …

  5. 4.1 Force - Physics | OpenStax

    Forces have different magnitudes and directions; this means that some forces are stronger than others and can act in different directions. For example, a cannon exerts a strong force on the cannonball …
