Human response times are eliminated from time measurement using light gates. if the stopwatch is damaged, the data logger terminates it.
<h3>What is speed?</h3>
Speed is defined as the rate of change of the distance or the height attained. it is a time-based quantity. it is denoted by u for the initial speed while u for the final speed. its si unit is m/sec.
To measure the speed of a toy automobile, it is preferable to utilize light gates and a computer as opposed to a stopwatch and a ruler.
Because Light gates eliminate the effects of human reaction delays for measuring time. is damaged,
The stopwatch is stopped by the data logger. With no reaction time, the uncertainty is substantially reduced.
The average speed may be determined by measuring the distance between the two light gates.
Hence, it is better to use light gates and a computer than to use a stopwatch and a ruler to measure the speed of a toy car.
