Physics: Physics is a branch of science which deals with physical quantities. In detail, Physics is the study of nature and phenomena occurring in nature. In the study physicists try to discover the rules or laws that are operating in nature, on the basis of observations, comparisons, experiments and analysis.
Fundamental forces in nature
In Physics there are many forces. Among those four are considered as fundamental forces. Those are
1) Gravitational force 2) Electromagnetic force
3) Strong nuclear force 4) Weak nuclear force.
1) Gravitational force:
Gravitational force is the force of mutual attraction between any two massive bodies by virtue of their masses.
These forces are
a) very weak in nature
b) long-range forces
c) independent of medium between them
d) depends upon the product of the magnitude of the masses
e) inversely proportional to the distance between the masses
f) always along the line joining the two masses
g) only attractive.
