magine a scenario in which an animal's force is pushing itself forward 5 N, friction is pushing it 4 N backward, gravity is pushing the animal 10 N down, and the animal is pushing itself 10 N up. Describe the movement of the animal.(1 point) Responses It moves forward and upward because those are the greatest net forces. It moves forward and upward because those are the greatest net forces. It moves 29 N forward because that's the net force. It moves 29 N forward because that's the net force. It only moves forward because there is a net force forward. It only moves forward because there is a net force forward. It moves 10 N down and 10 N up as those are the greatest forces acting on the animal. It moves 10 N down and 10 N up as those are the greatest forces acting on the animal.

To analyze the scenario:

  • The forward force is 5 N.

  • The backward friction force is 4 N.

  • The net forward force is 5 N - 4 N = 1 N forward.

  • The upward force is 10 N.

  • The downward gravity force is 10 N.

  • The net vertical force is 10 N - 10 N = 0 N.

With these calculations, the animal has a net force of 1 N forward and 0 N vertically (meaning no vertical movement).

Therefore, the correct response is: "It only moves forward because there is a net force forward."
