what is meaning of -2 and -1 in the formula of motion [m/s-²] ( unwanted spam will be reported and no points for u and I will make brainlist who told this nicely ❤️)
Answers
Answer:
If I understood the question correctly, ms*-2 is the SI unit of acceleration.
It can also be written as m/s*2.
As acceleration = velocity/ time and velocity = length/ time,
we basically get acceleration = length/ time*time = length/ time*2
The SI unit of length is metre and the SI unit of time is second, therefore the SI unit of acceleration becomes meter per second squared.
[The reason we prepare SI units based on length and time only is because they are fundamental units, along with the unit for mass( kg ).]
[ NOTE: Here the * mark denotes power or exponent. ]
Answer:
It means :meter per second square (ms^-2)
Other meter per square only.
Negative sign come in "second" present in dominator only after it get up in denominator its sign get INVERSE
