A force is a push or pull that acts upon an object as a result of that objects interactions with its surroundings. The strength of a force is measured in newtons (N). The concept of force is commonly explained in terms of Isaac Newton’s three laws of motion. A force is always a push, pull, or a twist, and it affects objects by pushing them up, pulling them down, pushing them to a side, or by changing their motion or shape in some other way. It has a magnitude and a direction. One of the foundation concepts of physics, a force may be thought of as any influence which tends to change the motion of an object. In physics, a force is an action that can cause an object to change its velocity or its shape, or to resist other forces, or to cause changes of pressure in a fluid. Understand how force affects motion, direction, and physical interactions. Force is an external agent capable of changing a body’s state of rest or motion. Push and pull come from the objects interacting with one another. force is the general term and implies the overcoming of resistance by the exertion of strength, power, or duress. Jan 15, 2026 · Force, in mechanics, any action that tends to maintain or alter the motion of a body or to distort it. Terms like stretch and squeeze can also be used to denote force. . When one object exerts a force on another object, the second object exerts an equal and opposite force on the first. Because force has both magnitude and direction, it is a vector quantity. Force calculations are widely used in physics to analyze the motion of objects and predict their behavior under various conditions. Mar 30, 2022 · The force on an object equals the object’s mass multiplied by its acceleration. The standard unit of force is the Newton (N), which is defined as the force required to accelerate one kilogram of mass at the rate of one meter per second squared. There are four fundamental forces in physics. In physics, a force is an action that can cause an object to change its velocity or its shape, or to resist other forces, or to cause changes of pressure in a fluid. In this Lesson, The Physics Classroom differentiates between the various types of forces that an object could encounter. In this Lesson, The Physics Classroom details that nature of these forces, discussing both contact and non-contact forces. May 7, 2025 · Learn about force: its definition, meanings, types, uses, and real-life examples. Our present understanding is that there are four fundamental forces in the universe, the gravity force, the nuclear weak force, the electromagnetic force, and the nuclear strong force in ascending order of strength. What is Force? Push or pull of an object is considered a force. In Physics, force is defined as: The push or pull on an object with mass causes it to change its velocity. It is exerted by one object on another, influencing its speed, direction, or shape. Calculating force often involves using Newton’s Second Law (F=ma) and other related equations. In mechanics, force makes ideas like ' pushing' or ' pulling' mathematically precise. Jul 23, 2025 · Therefore, Force can be defined as a push, pull, or impact that causes a change in an object's motion. force, compel, coerce, constrain, oblige mean to make someone or something yield.
