What are Alpha and Beta decay?
In alpha decay it is when a particle is ejected at a high speed from the nucleus of an atom. Beta decay is another type of nuclear energy in the process of spontaneously converting into 3 different particles of a proton, electron, and a neutrino. When both occur weak nuclear force is present.
What is the electromagnetic force?
It controls repealing of objects and attraction between objects(like how obj can't touch)Combines electricity and magnetism. Close the two objects higher attraction or repulsion(inverse square law) gravitational forces increase with closer objects.
What is our current understanding of gravity?
It is Einstein's theory of relativity. It states gravity is envisioned as geometrical in nature and proposed that the presence of any object with mass warp dimension of space and time which he called space time.
What is the weak nuclear force?
It is a process of nuclear decay which makes things radioactive, which ocurrs in Alpha decay and Beta decay in the nucleus of an atom. Is also 10 trillion times weaker than strong nuclear force.
what is electrostatic force?
It is the force or force that makes synthetic clothes cling together.
North pole and south is attracted to what?
The north pole is attracted to the south pole and the south pole is attracted to the north pole.
what happens in nuclear fission?
The process going on inside the sun which involves the 1st three forces.
Which is the strongest Fundamental Force?
The strongest is the strong nuclear force, it is 100 times stronger than the electromagnetic force. Uses nuclear fusion between 2 protons. its power is very short, not even a centimeter and only operates in the nucleus of atoms.
What is the weakest Fundamental force?
The weakest force is Gravitational force, which was discovered by Isaac newton in 1687(law of universal gravitation that said that anything in the universe that had mass exerted by a gravitational force, that everything has mass), Then later improved by Albert Einstein with his theory of relativity.
