An intuitive definition of force —that is, a push or a pull—is a good place to start. We know that a push or a pull has both magnitude and direction (therefore, it is a vector quantity), so we can define force as the push or pull on an object with a specific magnitude and direction.
Sep 12, 2022 · We know that a push or a pull has both magnitude and direction (therefore, it is a vector quantity), so we can define force as the push or pull on an object with a specific magnitude and direction. Force can be represented by vectors or expressed as a multiple of a standard force.

In physics, a force is an influence that can cause an object to change its velocity, i.e., to accelerate, meaning a change in speed or direction, unless counterbalanced by other forces. The concept of force makes the everyday notion of pushing or pulling mathematically precise.
These four basic forces are known as fundamental because they alone are responsible for all observations of forces in nature. The four fundamental forces are gravity, electromagnetism, weak nuclear force, and strong nuclear force.

•A force is a push or pull on an object.
•A net force is the sum of all of the forces acting on an object.
•When there is a net force on an object, the object will change speed in the direction of the net force. The object’s acceleration tells us how much it speeds up or slows down.
•The acceleration of an object depends on the size of the net force pushing or pulling it and the mass of the object.
•A larger net force creates a larger acceleration.
•A larger mass needs a larger net force to have the same acceleration as a smaller mass.
A force is used to describe how the motion of an object is affected by external agents. It is important to note that a force can be exerted by an inanimate being; that is, there is no intent - no conscious decision to push or pull - associated with a 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 capable of changing a body’s state of rest or motion. It has a magnitude and a direction.
