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 mechanics, force makes ideas like ' pushing' or ' pulling' mathematically precise. The meaning of FORCE is strength or energy exerted or brought to bear : cause of motion or change : active power.
How to use force in a sentence. Synonym Discussion of Force. 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.
Force Belly Stuffing, Because force has both magnitude and direction, it is a vector quantity. The force on an object equals the object’s mass multiplied by its acceleration. When one object exerts a force on another object, the second object exerts an equal and opposite force on the first. When multiple forces act on an object, the forces combine. Adding together all of the forces acting on an object gives the total force, or net force.
Force Belly Stuffing, An external force is a force that acts on an object within the system from outside the system. 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. (Pushing a pebble clearly takes less force than pushing a boulder, and pushing a boulder quickly obviously takes more force than pushing it slowly.) What is now known as Newton's second law of motion sets down this relationship quantitatively: Force equals mass times acceleration, or F = ma. Force in physics is a push or pull that can change the motion, shape, or direction of an object. Learn types of forces and Newton’s laws.
