Imagine a scenario in which an animal is pushing itself forward with a force of 5 N and friction is pushing it 4 N backward. Meanwhile, gravity is pushing the animal 10 N down, and the ground is pushing it 10 N up. Which statement best describes the movement of the animal?
Responses
1) It moves forward and upward because those are the greatest net forces.
2) It moves 10 N down and 10 N up as those are the greatest forces acting on the animal.
3) It moves 29 N forward because that's the net force.
4) It only moves forward because there is a net force forward.
The correct answer is:
4) It only moves forward because there is a net force forward.
