procedural memory

Explanation:

The procedural memory is where we keep, the more or less automatic learning, escaping consciousness. Essentially motor skills and processes, such as writing or cycling. No one thinks of the sequence of movements we have to perform so that we can ride a bicycle, nor can we describe in words how to do it. It's automatic, which is beyond our consciousness, so we don't need to think to do it.

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.

fossil fuels burn

cities become more industrialized
