- Force can be represented by vectors or expressed as a multiple of a standard force. The push or pull on an object can vary considerably in either magnitude or direction. For example, a cannon exerts a strong force on a cannonball that is launched into the air. In contrast, Earth exerts only a tiny downward pull on a flea.

In science, force is the push or pull on an object with mass that causes it to change velocity (to accelerate). Force represents as a vector, which means it has both magnitude and direction. In equations and diagrams, a force is usually denoted by the symbol F.
Force is everywhere and it comes in a variety of sizes, directions, and type. We can define Force as the push or pull of an object. Learn Force definition, unit & types of Force with solved examples.
- Gravity is the weakest force as its coupling constant is small in value.

The SI unit of force is the newton (N), which is a kilogram meter per second squared (kg·m/s2). Other common units include: 1. dyne 2. kilogram-force (kilopond) 3. poundal 4. kip 5. pound-force
The Greek philosophers Aristotle and Archimedes studied force, but believed constant motion requires a constantly applied force. Galileo Galilei and Sir Isaac Newton corrected this misperception and described force mathematically. Galileo’s inclined plane experiment (1638) mathematically described naturally accelerated motion. Newton’s three laws o...
Forces exist all around us in the everyday world. For example: 1. Friction is a force that opposes motion. 2. Applied force is the force applied to an object by a person or other object. 3. Centripetal forceis a force acting on a body moving in a circular path that is directed toward the center of the circle. 4. Centrifugal forceis an apparent forc...
The four fundamental forces of nature are gravity, electromagnetism, the strong interaction, and the weak interaction. 1. Gravity is the attractive force between two masses. It acts over an infinite distance, but is the weakest of the fundamental forces. 2. Electromagnetism describes the attraction and repulsions of electrical charges and magnets. ...

A force is a push or a pull that acts on an object due to the interaction with another object. Force is measured in newtons (N).
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.
