Question
3.2 Test (CST): Energy
Question 6 of 10
During practice, a soccer player kicks a ball and sends it
rolling across the grass. Over a short distance, the ball
slows down and stops.
/hich two statements support the idea that energy is conserved in this
xample?
• A. Chemical energy in the soccer player's body was converted into
kinetic energy during the kick.
B. The potential energy of the ground increased as the kinetic
energy of the ball decreased.
Some of the ball's kinetic energy was converted into thermal
energy due to friction.
• D. The kinetic energy of the ball was gradually destroyed as the b
rolled along the ground.
