11 You would like to confirm Netwon's second law by running an experiment. You decide to drop two different objects from a tall building and discover that one of t objects lands on the ground five seconds before the other object. What can you conclude? A Newton's second law is not valid because each object should experience the same force of gravity and therefore should land at the same time. B There is some other force present. This additional force is different for the two objects and accounts for the fact that the objects land at different times C Newton's second law is not relevant in determining when an object will land on the ground. D One object must be heavier than the other and must therefore experience a greater gravitational acceleration. 12 According to the universal law of gravitation, if you double the masses of both attracting objects, then the gravitational force between them will: A B C Not change at all. Increase by a factor of 2. Decrease by a factor of 2. D Increase by a factor of 4.
