In physics, force is a physical quantity that describes the interaction between two objects that results in a change in motion. Force can cause an object to accelerate, decelerate, or change direction. It is typically represented by the symbol "F" and is measured in the unit of newtons (N).
Force can be caused by several types of interactions, including gravitational attraction, electrostatic attraction or repulsion, and contact interactions between objects. Force is a vector quantity, which means it has both magnitude and direction. The magnitude of force is usually measured using a device called a force meter, which is calibrated to read the force in newtons.
Some common examples of forces include gravity, friction, tension, and normal force. These forces can be described mathematically using principles of physics, such as Newton's laws of motion, and can be used to explain and predict the behavior of objects in motion.
