However, energy

The law of conservation of energy states that energy cannot be created or

can be blank

from one substance to another.

You stand sideways in a moving train. Estimate how far apart you should keep your feet so that when the train accelerates at 3.2 m/s2 you can still stand without holding anything. Let d be the distance of separation between your feet, and h = 0.
