I am trying to find out how gravity effects mass. What I’m going to do is compare objects with different masses. I am going to time the object when I drop it, measure the height I dropped it from, and divide distance and time.
When certain stars stop shining it eventually collapses. If a star is three times bigger than the sun when it collapses it will form a object called a black hole. Black holes have the strongest pull of gravity. Its so strong that even light, the fastest thing in the universe, can not escape.
