Question

Imagine 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.

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.

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.

Answer 1

The vertical forces cancel (10 N up and 10 N down → net 0 N). Horizontally, 5 N forward − 4 N backward = 1 N forward. So there is a net force of 1 N forward, and the animal accelerates forward.
