Newton’s Laws Instructions: Print the guiding questions and use them to write your answers as you read or watch the instructional media (reading, video, radio podcast, computer simulation, etc.). Type the number of the question and your answer (do not re-copy the original question) and send the completed report to Blackboard’s SafeAssign. For all questions, answer in your own words (paraphrase). Answers that are directly copied from any internet source, including the instructional media studied, will receive no credit. Newton’s Laws

1. State (in words) Newton’s second law. 2. In the equation F = ma, what must “F” and “a” always have? 3. Applying F = ma for free falling objects, we can conclude that the force of gravity

produces a _____ _____to a mass m. 4. What two forces are always acting on a falling object (after it is released)? 5. State Newton’s first law. 6. What is an alternate way of writing Newton’s second law? 7. State Newton’s third law. 8. In the David and Goliath example, why wasn’t the confrontation as uneven as originally

portrayed? 9. According to Galileo, what two types of simultaneous motions do all projectiles have in

common? 10. For falling objects, describe the velocity and acceleration for each of the two types of

simultaneous motions. 11. What incorrect medieval idea was used to try to explain the motion of projectiles? 12. What is the difference between the contributions of Galileo and Newton to the study of

motion? 13. In the “shoot the monkey” experiment, where must the pistol be aimed at for the bullet to

reach its target?
