how do kinetic energy, gravitational potential energy and heat due to friction change as the marble rolls down the ramp

Kinetic energy (motion) increases as it rolls down the ramp because it accelerates and moves faster.

gravitational potential energy decreases as it rolls down because less energy is stored in the position of the ball and more is in is motion.

heat will increase because the ball rolling down the ramp is not 100% efficient. some friction is involved which generates heat.
