The document discusses several examples of forces acting on objects: 1) A sign experiencing a net force of 10N from forces of 50N acting in different directions. 2) Mike experiencing net force of 100N from equal and opposite forces. 3) A sign moving right with a net force of 30N, so the force to the right must be 30N. 4) Nemo accelerating in a stream due to unbalanced forces. 5) A sign falling with a net force of 1500N from forces of 1050N and 2000N. 6) For Violet to be at rest, the forces on her must be equal at 50N.
