I need help with three issues related to physics:]?

1. Why shoes athletes often have spots on them? 2. when falls a golf ball on the pavement, it bounces up. It is a strength to make it bounce up? If so, exerting force? 3. You are a journalist a local television station and would like to give their stories a touch of physical science. Write a story for the evening news in which you describe an event in terms of the forces involved. Use a catchy title. Thanks <33

1. I think they are the self-heeled shoes. They are lighter than tennis or normal functioning of shoes for athletes is the reason for using them. They also have peaks that provide traction to avoid slipping and sliding across the grass. 2. I'm pretty sure the force is created by the impact of elastic collision against the pavement. The golf ball is pushing against the pavement and actually makes a bit but, Obviously, the land will not yield much energy that goes back to the ball as it bounces up. (I think! Not 100% sure) 3. OMG METEORS Meteors are hitting the Earth because they entered the PULL OF THE EARTH AND GRAVITATION going to kill U.S. ALL!
