A tall Styrofoam cup is filled with water. Two holes are punched in the cup near the bottom, and water begins rushing out. If the cup is dropped so it falls freely, will the water continue to flow from the holes? Explain.
We have to explain whether water will come out from the holes of the cup, when the cup is freely dropped.

A difference in pressure across the body, causes a push on the body from the high pressure region to the low pressure region.
