What is Force?
Force is an invisible physical phenomenon that acts upon objects and affects their motion It is an invisible energy that has the capacity to cause acceleration, deceleration, rotation, or change in the direction of motion of an object. Force can be divided into two types: unbalanced forces and balanced forces. Unbalanced forces occur when two or more unequal forces are applied to an object, resulting in a net force that causes motion. This motion can be accelerated, decelerated, or reversed. Balanced forces, on the other hand, occur when multiple forces applied to an object produce a net force of zero, resulting in no change in motion.
Force is often measured in Newtons, which is a unit of force that is equal to the force needed to accelerate an object with a mass of one kilogram at a rate of one meter per second squared. Force can also be measured in terms of weight and mass, but these measurements differ depending on the gravitational force of the object being measured.
The idea of force is an essential part of physics and can be applied to many areas, from everyday life to space exploration. In physics, the four fundamental forces that govern the behavior of the universe are gravitational force, electromagnetic force, weak nuclear force, and strong nuclear force.
