The scientific use of "digital" is usually used to describe signals and other entities that have an "either/or" value. An example is the binary system where 1 represents an "on" and 0 represents an "off"
The common use of digital implies anything that is electron, be it analogue or digital.
The equation for kinetic energy is KE=1/2mv^2
So if the small vehicle AND the large vehicle both had the same speed, the large vehicle would have more kinetic energy since it has greater mass, resulting in a much more larger stopping distance than the smaller car.
B evaporation since the water is going up
Newtons first law states "an object at rest will stay at rest while an object in motion will remain in motion" im confused as to what you are asking for but heres an example.
a car traveling at a speed of 35mph coming up to a stop sign has to slow down to a stop it cant stop instantly thats the same for it accelerating.
