  1. 5N + 5N can equal as little as 0N because they could be going in opposite direction and at most 10N when they are going in the same direction.

  2. 5N + 5N = 0N because, equal forces moving in opposite directions means the object is stationary.

  4. If the two are moving towards each other then 5N + 5N equals 0, but we can't be sure because we don't know the direction.

  6. equal foces moving in oppisite directions mean the object is stationary example 5N+5N=0N

  7. 5N +5N depending upon the direction that the Newtons are heading in can equal either 0N, 10N, or another value in between 0N and 10N.

  8. an equilibrium is when forces are equally pulling against eachother.

  9. 5N + 5N could have different answers depending on the direction of the forces. the answer could be as high as 10N when the forces are in the same direction and as low as 0N when the forces are pulling equally in opposite directions.

  10. 5N+5N could equal 0N if the forces were opposite, 10N if they were on the same side, or any number in between depending on the angle of the two forces.

  11. if two equal forces go in opposite directions then the force will become 0N, ex: 8N+8N=0.

  12. We would need the direction in order to find out the exact answer for this. It would be zero if the forces are acting against each other and would be 10N if the two forces were going in the same direction.

  13. 5N+5N equals 0N if they are going opposite directions. If they are going the same direction then 5N+5N equals 10N

  14. Lot's of quoting going on here... perhaps we should post our own comments in addition to the quotes
