how serious is the challenge to physics to explain the causes behind every force that we know of?and is physics trying to get over its scientists differences of approaches in this regard?
interestedman said:thank you dr chinese,i mean,the causes or the initiators ,the mother force if you like,that has caused the laws to exist?,the initial cause or determinent behing them,could these forces be relegated to a single creating force?if yes why and if no why is that.
interestedman said:thanks freeman,is there any online resource for the ultimate explanation?
DrChinese said:At this point, the standard model has 3 quantum forces (strong, weak, electromagnetic) plus general relativity (gravity). I don't see that there is much that really explains why the laws of physics are as they are, nor why there is something rather than nothing. Most of this is currently considered more or less as free parameters that could have conceivably have occurred another way.
interestedman said:dear dr chinese,what do you mean "could have conceivably have occurred another way",thanks.
Force is a physical quantity that describes the interaction between two objects. It can be described as a push or pull on an object that causes it to accelerate or change its motion.
Forces are measured using a unit called Newtons (N). One Newton is equal to the force required to accelerate a mass of one kilogram at a rate of one meter per second squared (1 N = 1 kg * 1 m/s^2).
Contact forces are those that require physical contact between two objects, such as friction or tension. Non-contact forces, on the other hand, do not require physical contact and can act over a distance, such as gravity or magnetic forces.
Newton's laws of motion describe how forces affect the motion of an object. The first law states that an object at rest will remain at rest, and an object in motion will remain in motion at a constant velocity unless acted upon by an external force. The second law states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. The third law states that for every action, there is an equal and opposite reaction.
"Common ground" refers to the idea that all objects in the universe are subject to the same fundamental forces, regardless of their size or composition. This means that the same laws of physics apply to all objects, whether they are microscopic particles or massive planets.
