What does si stand for when referring to a system of measurement

The International System of Units (SI, abbreviated from the French Système international (d'unités)) is the modern form of the metric system, and is the most widely used system of measurement.

Système international (d'unités)

Explanation:

The full form of SI is Système international (d'unités). It started around the 18th century. It is known as the International System of Units in English. The basic units of the SI system are second, kilogram, Ampere, Kelvin, mole and candela. All other units are obtained by the combination of these units. The SI system of units are used in almost all the countries of the world.

what is the actual question though?

note: the given question is incomplete.

complete question is given below.

which is an example of kinetic energy?

a. the energy stored in ethanol  

b. a hockey puck sliding across the ice  

c. a compressed spring  

d. a ball sitting at the top of a ramp

solution: the kinetic energy is the energy posses by the virtue of the motion of the object.

in the given options, a, c and d are the example of potential energy because it is the energy posses by the virtue of the rest of the object. but option b has the kinetic energy as the object is in motion.

hence, a hockey puck sliding across the ice   is the apex example of kinetic energy.

so, the option (b) a hockey puck sliding across the ice   is the correct option.
