What are the forces of physics?

Physical forces are external objects or substances that cause to change the movement of other free objects or stress in solid objects or bodies. Simply put, the strength uses pressure or pull on an object that causes to change the direction, change speed or to some extent. Physical forces are in size and direction, which makes them a vector amount for mathematical purposes. There are many different types of forces, from simple physical objects that collide to complex electromagnetic fields repelling different objects. Scientists still do not fully understand the functioning of forces, because many such as gravity are naturally associated with the predominantly unknown field of quantum physics.

There are many different physical forces that have been observed and are used in physics calculations. Applied forces are generally considered to be the simplest forces. Although most types of forces can usually be considered as applied forces, the deadline is usually reserved, often human, which directly push or pullu on the system. Another common and important force is known as normal force. Normal force is the same force applied by an object as the floor when another object exerts pressure on it; This power is the reason why people do not come to the ground when they pass it.

One of the most important forces is gravity that has not been identified as a force to the work of Isaac Newton. Gravity meets the definition of force because it causes a change in the movement of objects. Of course, the ball thrown into the air will return to the ground due to gravitational force. Electromagnetic forces are also commonly studied physical forces involving strokes and repellation between differently charged objects.

Nuclear forces are an integral part of a study of physical forces, especially in the field of quantum physics. There are two primary types of nuclear forces, strong nuclear power and weak nuclear power. Strong nuclear force is a force responsible for holding together subatomical particles,that form the core of the atom, and the weak atomic force is involved in the disintegration of subatomical particles.

There are also many other types of forces. All the forces of physics, however, do the same in a very different way and on very different scales. They cause change, usually related to movement, in other objects. Many physical forces are interconnected and can have different effects.
