F = N*μ or F =m*g*μ
Explanation:
The friction force is defined as the product of the normal force by the corresponding friction factor.
When a body is in equilibrium over a horizontal plane its normal force value shall be equal to:
if we simplify this formula more for a balanced body on a horizontal plane, we will have.
An interval of 1 degree Celsius is equal to 1 Kelvin
Explanation:
There are different scales used for measuring temperatures. The most common ones are:
- Celsius scale: it is set by the following convention: the zero in this scale is placed at the freezing temperature of the water, while the 100 degrees is placed in corresponding to the boiling point of water. The the scale is divided into 100 equal intervals between these two points. Temperatures in this scale are indicated with the Celsius degree (.
- Kelvin scale: it is set such that the absolute zero (the temperature at which particles in matter stop to have any motion) is placed at zero in this scale. A difference of 1 degree in this scale is equal to 1 degree Celsius. Temperatures in this scale are indicated with the Kelvin (K).
The conversion between the two temperatures is:
So for example, the absolute zero () corresponds to
in the Celsius scale. However, intervals between two temperatures are measured in the same way in the two scales: therefore, an interval of 1 degree in the Celsius scale is equal to an interval of 1 Kelvin in the Kelvin scale.
