Answer

Explanation:

Step1: Analyze water in dam

The water at a height in the dam has gravitational - potential energy due to its position relative to the lower levels.

Step2: Identify kinetic energy in water in dam

When the water is released and starts flowing downwards (e.g., through turbines), it has kinetic energy because of its motion.

Step3: Determine energy conversion in water in dam

Potential energy becomes kinetic when the water is allowed to fall from its elevated position in the dam.

Step4: Analyze archer's bow

The bow has elastic - potential energy when it is drawn back, as the bowstring and the bow are deformed.

Step5: Identify kinetic energy in archer's bow

When the bowstring is released and the arrow is propelled forward, the arrow has kinetic energy.

Step6: Determine energy conversion in archer's bow

Potential energy becomes kinetic when the bowstring is released and the stored elastic - potential energy is transferred to the arrow as kinetic energy.

Answer:

Group 1: Water in a Dam

  • Where is potential energy present? The water at the higher levels in the dam has gravitational - potential energy.
  • Where is kinetic energy present? When the water is flowing out (e.g., through turbines).
  • When does potential become kinetic? When the water is allowed to fall from its position in the dam.

Group 2: An Archer's Bow

  • Where is potential energy present? In the drawn - back bowstring and bow (elastic - potential energy).
  • Where is kinetic energy present? In the moving arrow after the bowstring is released.
  • When does potential become kinetic? When the bowstring is released.
