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 ' …

force, compel, coerce, constrain, oblige mean to make someone or something yield. force is the general term and implies the overcoming of resistance by the exertion of strength, power, or duress.

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 details that nature of these forces, discussing …

Jan 15, 2026 · 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 …

The Army, Marine Corps, Navy, Air Force, Space Force and Coast Guard are the armed forces of the United States. The Army National Guard and the Air National Guard are reserve components of their …

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. Our present understanding is that there are four fundamental forces …

Terms like stretch and squeeze can also be used to denote force. In Physics, force is defined as: The push or pull on an object with mass causes it to change its velocity. Force is an external agent …

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.

Force is push or pull. Unbalanced forces make an object accelerate. Forces on an object are usually balanced: forces in one direction are equal to forces in the opposite direction: No acceleration. …

The strength of a force is measured in newtons (N). There are four fundamental forces in physics. A force is always a push, pull, or a twist, and it affects objects by pushing them up, pulling them down, …
