select the correct answer. what happens to the sum of the balls kinetic energy and potential energy as the ball rolls from point a to point e? assume theres no friction between the ball and the ground. a. the sum decreases. b. the sum increases. c. the sum remains the same. d. the sum always equals zero.
Answer
Answer:
C. The sum remains the same.
Explanation:
Step1: Aplicar ley de conservación de energía
En ausencia de fricción, la energía mecánica (suma de energía cinética y potencial) se conserva.
Step2: Analizar el movimiento de la bola
La bola cambia entre energía potencial y cinética, pero su suma total no varía.
