|
It is a weak force |
It is a strong force |
|
The force is <nobr>F=(GM1M2)/R2</nobr> (G= gravitational constant) |
The force is F=mg (g=acceleration due to gravity) |
|
The direction of gravitational force lies in the radial direction from the masses |
The direction of force of gravity is along the line joining the earth’s center and the center of the body. Its direction is towards the center of the earth. |
|
Gravitation force is a vector quantity |
Gravity is a vector field |
|
The force can be 0 when separation between bodies is infinity |
The force of gravity can be 0 at the center of the earth |
|
It requires two masses |
It requires only one mass |

The evaporation of the sweat is actually what cools you. The changefrom a liquid to a gas requires heat energy and it gets part ofthat heat energy from the skin, making the body feel cooler. Perspiration takes excess heat from your body and releases it tothe surface in moisture. A secondary mechanism continues to coolthe body as the moisture evaporates from the surface of the skin.Cooling occurs in all types of climates but the evaporationmechanism works best in areas with low humidity because it exchangeis more rapid.
