Two influential product that Tesla (Elon Musk) made is his Model X, and his power wall. The Model X revolutionised cars and driving in general, with self driving, and many components to help. The powerwall made electricity another level. Along with his solar-shingle roof, it made homes efficient, and 'green'.
Serbian-American engineer and physicist Nikola Tesla (1856-1943) made dozens of breakthroughs in the production, transmission and application of electric power.
He invented the first alternating current (AC) motor which is used all over the world in business, factories and power plants.
He developed AC generation and transmission technology that we still have as the main form of delivering power to all consumers nowdays.
because energy will be lost due to friction, sound, and heat (arguably similar to friction) and ENERGY MUST STAY THE SAME so it is IMPOSSIBLE for the ball to bounce higher than when dropped!
