In the international system of units, the basic unit of mechanics is () A. N、m、sB. N、kg、sC. kg、m、sD. N、kg、m
There are seven basic physical quantities: length, mass, time, thermodynamic temperature, electric current, light intensity and quantity of matter. Their units in the international system of units are called basic units. Newton (n) is the derived unit. So option C is correct. So option C is selected
What are the three basic units of mechanics in the international system of units
rt
The three basic units in mechanics are m (meter), kg (kilogram) and S (second);
They are the units of length, mass and time
The rest are derived from them
For example, n = kg * G
Speed = m / S
In the international system of units, what is the unit of speed and what does it read and do
m/s
Read meter per second
What does SI unit mean?
International system of units, from the French Le syst è me international d'unit é s, referred to as Si
In 1960, the International Conference on Metrology established the international system of units on the basis of the meter, kilogram and second systems
