Answer:
distance and length are the same quantity
Gravity is the cause of . . .
-- star formation,
-- planet formation,
-- orbits.
So without gravity, there pretty much wouldn't be any solar or any system.
The truth is both of them are more reactive metal.
The Metric, and the US Standard systems. :)
Acceleration = (change in speed) / (time for the change)
change in speed = (ending speed) - (starting speed)
change in speed = (10 m/s) - (2 m/s) = 8 m/s
Acceleration = (8 m/s) / (4 sec)
Acceleration = (8/4) (m/s²)
<em>Acceleration = 2 m/s²</em>
