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. The SI unit of force is the newton (N), and force is often represented by the symbol F.
Force is a vector quantity, meaning it has both magnitude and direction. The symbol for force is the capitol letter F. A famous example of an equation for force is Newton's second law: F = m*a. Here F is force, m is mass, and a is acceleration. This law states that a net force equals the rate of the change of its momentum with time.
Force can change the state of rest or motion of an object. Force will cause a change in motion, for example, the force exerted by the motor of the car will enable the car to move, while force exerted by the brake will enable the car to stop. Force Formulas. Force is defined by the product of the mass and acceleration of the object.
When all the forces acting on an object are balanced, the net force acting is zero. But, if all the forces acting on a body result in an unbalanced force, then the unbalanced force can accelerate the body, which means that a net force acting on a body can either change the magnitude of its velocity or change the direction of its velocity.
In physics, a force is a push or pull or a twist between objects.It is called an interaction because if one object acts on another, its action is matched by a reaction from the other object. [1] This idea is known as Newton's third law, [2] where action and reaction are "equal and opposite" [3] (matched).The objects are just the things the force acts between. . Different forces act between ...
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 set forth in his Principia Mathematica (1687). According to Newton's first principle, a body that is at rest or moving at a uniform rate in a straight line will remain in that state until some force ...

The force is proportional to the product of the two masses and inversely proportional to the square of the distance between them: [11] Diagram of two masses attracting one another = where F is the force between the masses; G is the Newtonian constant of gravitation (6.674 × 10 −11 m 3 ⋅kg −1 ⋅s −2);
