Which answer best describes the flow of electrical charge?
from a higher to a lower potential energy
from a lower to a higher potential energy
from a higher to a lower kinetic energy
from a lower to a higher kinetic energy

Answer : Option A) Higher potential to lower potential.

Explanation : An electric current can be defined as a flow of electric charge. In electric circuits this charge is often carried by moving electrons in a wire which are in opposite direction of current. The charge is often flowing from the higher potential to lower potential energy.

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.
