Q.4) An archer stretches the string of his bow to shoot an arrow.
i) Name the type of energy he uses in the process.
ii) the type of energy into which it is converted.
Answers
Answer:
a muscular energy is converted into kinetic energy
because while stretching the string he uses his arms he uses his muscular and when the arrow is released it produces kinetic energy
Answer:
(i) The type of energy he uses in the process is Mechanical Energy.
(ii) It is converted from Potential Energy to Kinetic Energy.
Explanation:
CONCEPT APPLIED- "Energy can never be created nor be destroyed, it can only transform from one form to the other".
Explanation of the first part- In the process, the Archer stretches the arrow through the Mechanical Energy applied by him to reach a threshold level ( the level where the bow's string has been stretched to its maximum).
At the threshold position, the arrow has gained some Potential energy.
Explanation of the second part- Now, on releasing the arrow, this Potential energy changes to Kinetic energy, and on releasing the arrow, it has gained velocity because of the conversion of this energy.
