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 motion. Because force has both magnitude and direction, it is a vector quantity.

Learn what force is, how to measure it, and what types of forces exist in physics. Find examples, formulas, and solved problems on force and its effects.
A force is an influence that can cause an object to change its velocity unless counterbalanced by other forces. The concept of force makes the everyday notion of pushing or pulling mathematically precise. Because the magnitude and direction of a force are both important, force is a vector quantity.
30 Μαρ 2022 · Learn what a force is in physics and other sciences, how to measure it, and what types of forces exist. Find out the history, examples, and fundamental forces of nature.
Learn the definition of force as a push or pull resulting from an interaction between two objects. Explore the types of forces, such as contact and action-at-a-distance forces, and how to represent them using vectors and diagrams.
Learn the intuitive and quantitative definitions of force as a push or pull with magnitude and direction, and how to draw free-body diagrams. Explore the SI unit of force, the newton, and the laws of motion.
3 Ιουλ 2019 · Force is a vector; it has both direction and magnitude. The SI unit for force is the newton (N). One newton of force is equal to 1 kg * m/s2 (where the "*" symbol stands for "times"). Force is proportional to acceleration, which is defined as the rate of change of velocity.
