group practice - energy poster: energy poster checklist: both potential and kinetic energy is present in every scenario. with your group design a poster that clearly: displays the motion of the scenario. states where and how energy is present in the scenario. states what type of energy is present at this point. **scholars should be able to understand your poster without an explanation, let the poster speak!** group 1: water in a dam: - where is potential energy present? - where is kinetic energy present? - when does potential become kinetic? group 2: an archer’s bow: - where is potential energy present? - where is kinetic energy present? - when does potential become kinetic?
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.
