Question

What is common between flow of current, water, heat and free-falling body

• A. All are same
• B. All move from high to low potential
• C. All move from higher density to lower density
• D. All have same universal constant

Answer 1

The correct option is B All move from high to low potential

Current flows from higher potential to lower potential. Water flows from higher pressure to lower pressure.

Heat flows from higher temperature to lower temperature. Free falling body falls from higher potential to lower potential.
