The letter r is the distance from you to what’s pulling you. A neat fact is that for something like the earth you can pretend that all of the mass between you and the center of the earth is pulling you from the center of the earth. But when you start falling, things start changing. As you fall there is less and less mass between you and the center so there is less and less to pull you down. But wait! You are closer to the center and the closer you are to what’s pulling you the harder you will be pulled. Acceleration tells you how fast your speed is changing, or how quickly you are falling more quickly. Newton came up with a mathematical way to relate a force, such as gravity, and acceleration, F=ma. In the case of falling through the earth it is gravity that is causing the acceleration so we say that gravity is the force in this equation. When you are on the surface of the earth the acceleration due to gravity is 9.8 m/s 2. The acceleration due to gravity depends on the mass that’s pulling so once you being to fall, your acceleration gets smaller.The mathy way to write this is
