However, based on the current knowledge, it is likely that foam rolling helps to free up knots and adhesions that may have formed between the tissue. Moreover, if used correctly (e.g., slow-rolling, breathing, and relaxing on a comfortable roller), it is also likely that foam rolling helps relax the nervous system.

Learn MoreIt received a major update in February 2022. How a roller coaster achieves its top speed all comes down to energy. Energy is a conserved quantity that flows when there is a change. Energy is stored in an object: mass (e=mc2) and kinetic energy. Energy may also be stored in a field.
Learn MoreThat can take a while, because some rollercoasters start off around 100m (330ft) in the air! The winch has to use energy to pull the rollercoasters up the hill, but that energy doesn''t simply disappear. The rollercoaster cars store it just by being up in the air—and the higher up they are, the more energy they store.
Learn MoreAlthough you use energy as you climb, your body and the boulder also gain energy—potential energy. When the boulder is at the top of the hill, you can let it go so it rolls back down again. It can roll down because it has stored potential energy. In other words, it has the potential to roll down the hill all by itself.
