Beginning from distances 10^-35 m the gravitation force becomes in 40 times larger than its usual macroscopic value and in 10^41 times larger for the distance ~10^-54 m. Numerical evaluations of the fations gas energy density (5.0445x10^109 J/m3), of gravitational cross-section of the ...
The gravitational force of the earth can be observed every time a ball is thrown into the air and falls back to the ground. Earth's gravity makes rivers flow, and it even holds earth's moon in its orbit. Earthrise, a photo from the Apollo 8 mission. The strength of an object's g-...
Types of Force There are various types of Force that act on an object. Here are some of Force applied on an object generally: Muscular Force Mechanical Force Frictional Force Gravitational Force Electrostatic Force Magnetic Force Let’s take a look at the Types of Force in detail: Muscular For...
Because force has both magnitude and direction, it is a vector quantity. The representation of forces by vectors implies that they are concentrated either at a single point or along a single line. This is, however, physically impossible. On a loaded component of a structure, for example, the...
