Which of the following energy transformations occurs to power the player's jump shot?Athermal energy to sound energyBlight energy to thermal energyCmechanical energy to electrical energyDchemical energy to kinetic energy
Question
A basketball player holds a basketball, ready to jump and shoot the ball. The player jumps in the air and shoots the ball toward the basket. Which of the following energy transformations occurs to power the player's jump shot?Athermal energy to sound energyBlight energy to thermal energyCmechanical energy to electrical energyDchemical energy to kinetic energy
Solution
The correct answer is D: chemical energy to kinetic energy. Here's why:
-
The player's body uses the food they have eaten, which is stored as chemical energy, to power their muscles.
-
When the player jumps and shoots the basketball, their muscles contract and move. This is kinetic energy, which is the energy of motion.
-
Therefore, the energy transformation that occurs is from chemical energy (in the player's body) to kinetic energy (in the moving basketball).
