2. In another set up (figure 2B), the ball is released from the same height as figure 2A. It speeds up and if it is rolling up another inclined surface that is not as steep as figure 2A, it slows down and reaches the same height. However, it covers a farther distance as it rolls up the slope. Figure 2B
3. In the last set up, the ball is released from the same height as figure 2A. This time it continues to roll on a flat surface. The ball does not speed up nor slow down (see Figure 2C) as if it continues to move forever. Figure 2C
