Consider Newton's first law of motion to determine which of the following statements are true? List all that apply. Newton's first law of motion is applicable to both moving and nonmoving objects. If a football is moving upwards and rightwards towards the peak of its trajectory, then there are both rightwards and upwards forces acting upon it. It would take an unbalanced force to keep an object in motion. If an object is at rest, then there are no forces acting upon the object. It would take an unbalanced force to keep an object in motion at a constant velocity. It is the natural tendency of all objects to eventually come to a rest position. A pendulum bob is set into its usual back-and-forth periodic motion. After some time (perhaps 10 minutes), the pendulum bob comes to a rest position. This is best explained by the idea of inertia - all objects eventually resist motion. If a 3-kg rock is thrown at a speed of 2 m/s in a gravity-free environment (presuming one could be found), then an unbalanced force of 6 N would be required to keep the rock moving at a constant speed. It would take an unbalanced force to cause an object to accelerate from rest.

Question

Consider Newton's first law of motion to determine which of the following statements are true? List all that apply.

  1. Newton's first law of motion is applicable to both moving and nonmoving objects.
  2. If a football is moving upwards and rightwards towards the peak of its trajectory, then there are both rightwards and upwards forces acting upon it.
  3. It would take an unbalanced force to keep an object in motion.
  4. If an object is at rest, then there are no forces acting upon the object.
  5. It would take an unbalanced force to keep an object in motion at a constant velocity.
  6. It is the natural tendency of all objects to eventually come to a rest position.
  7. A pendulum bob is set into its usual back-and-forth periodic motion. After some time (perhaps 10 minutes), the pendulum bob comes to a rest position. This is best explained by the idea of inertia - all objects eventually resist motion.
  8. If a 3-kg rock is thrown at a speed of 2 m/s in a gravity-free environment (presuming one could be found), then an unbalanced force of 6 N would be required to keep the rock moving at a constant speed.
  9. It would take an unbalanced force to cause an object to accelerate from rest.
