A student wrote: “The only reason an apple falls downward to meet the earth instead of the earth rising upward to meet the apple is that the earth is much more massive and so exerts a much greater pull.” Please comment .
Step 1 of 3
Solution 1DQ This situation can be explained by Newton’s law of gravitation and second law of motion. According to Newton’s law of gravitation, the gravitational force on the apple due to the earth and vice versa is the same. It means each one will pull the other with the same force. But the apple is much smaller than the earth. If we take Newton’s second law of motion into account, which says Force = mass × acceleration, considering both gravitational attraction forces to be equal, the acceleration of the apple will be much larger than the earth because of its much smaller mass than the earth. That is why we see the apple falling downward. The earth will also be pulled toward the apple, but with a negligible acceleration.
