How does the potential and kinetic energy of the ball change as the ball rolls down the hill?
a
The potential and kinetic energy of the ball both increase.
b
The potential and kinetic energy of the ball both decrease.
c
The potential energy of the ball increases, and the kinetic energy of the ball decreases.
d
The potential energy of the ball decreases, and the kinetic energy of the ball increases.
d
The potential energy of the ball decreases, and the kinetic energy of the ball increases.
