1. The fundamental interactions, also known as fundamental forces, are the interactions that do not appear to be reducible to more basic interactions. There are four conventionally accepted fundamental interactions or forces—gravitational, electromagnetic, strong, and weak. All forces in nature may be classified into four types. The gravitational force holds together the universe at large, plus the atmosphere, water, and us to the planet Earth. The electromagnetic force governs atomic level phenomena, binding electrons to atoms, and atoms to one another to form molecules and compounds. The strong nuclear force holds the nucleus together. The fourth force, the weak nuclear force, is responsible for certain types of nuclear reactions and has little bearing on energy sources today. Following statements about the fundamental forces are correct:
A fundamental force is a force that cannot be described in terms of other forces.
Strong nuclear forces are present in the atoms of every material.
Any interaction occurring anywhere in the universe can be explained in terms of the four fundamental forces.
Weak nuclear forces make nuclear waste dangerous.
The electrical energy produced in a nuclear power station can be explained in terms of electromagnetic and weak nuclear forces.
2. The gravitational force between a mass and the Earth is the object's weight. Mass is considered a measure of an object's inertia, and its weight is the force exerted on the object in a gravitational field. On the surface of the Earth, the two forces are related by the acceleration due to gravity: Fg = mg. This force is provided by gravity between the object and the Earth.
A molecule of sugar dissolved in a glass of water, A balloon filled with helium, A beam of light near a black hole,An elevator inside a building, an apple falling from a tree. So all these statements are significaly affected by the force of gravity except he old saying, “What goes up, must come down".
