- 5.1 Forces - University Physics Volume 1 | OpenStaxThe forces are represented by vectors extending outward from the free body. Free-body diagrams are useful in analyzing forces acting on an object or system, and are employed extensively in the study and application of Newton’s laws of motion.
- 4.1 Force - Physics | OpenStaxForces 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 that is launched into the air.
- Forces and Newton's laws of motion - Khan AcademyStart Unit test. The word force can take on different meanings—how is it used in science? Learn about what a force is and how a Isaac Newton's Laws of Motion changed the world's view of how forces and motion work.
- Force | Definition & Formula | BritannicaForce, 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 motion. Because force has both magnitude and direction, it is a vector quantity.
