perception distance.
This distance is called the 'Thinking Distance'.
The element of total stopping distance is called reaction distance. It is the distance a vehicle travels from the moment a driver perceives a hazard until the moment they physically react by applying the brakes.
Reaction time
The distance light travels in a year is called light-year
The distance a wave travels over time is called wavelength. It is the distance between two consecutive points in a wave that are in phase.
The horizontal distance a projectile travels is called range.
The distance that a wave travels in a certain amount of time is a wavelength. Wrong,it's speed.(:
No, the distance an object travels in unit time is called speed. The distance travelled per unit time in a specified direction is called velocity. The rate of change of velocity is called acceleration.
A light year
The distance a piston travels within the cylinder is called the stroke. It is the distance between the top dead center (TDC) and the bottom dead center (BDC) positions of the piston.
Santa travels in a sleigh pulled by reindeer.
That is called a light-year.
