Worked practice questions

Two tug-of-war teams pull equally hard in opposite directions. Such forces are called:

  1. Balanced
  2. Bounded
  3. Buffered
  4. Bundled
Show answer and solution

Correct answer: A. Balanced

1. The two pulls match in size but point opposite ways. 2. Neither one wins out over the other. 3. Such forces are balanced. _Source: syllabus Science Class IX, Chapter 6, How Forces Affect Motion._

One team then pulls harder and the rope moves, showing the forces have become:

  1. Unrelated
  2. Unbalanced
  3. Unattached
  4. Unreported
Show answer and solution

Correct answer: B. Unbalanced

1. The two pulls no longer match in size. 2. A leftover force acts along the stronger pull. 3. So the forces are unbalanced. _Source: syllabus Science Class IX, Chapter 6, How Forces Affect Motion._

Forces of 10 N and 6 N act on a block in the same direction. The net force is:

  1. 16 N
  2. 04 N
  3. 60 N
  4. 10 N
Show answer and solution

Correct answer: A. 16 N

1. Same-direction forces add together. 2. 10 plus 6 gives sixteen. 3. The net force is 16 N. _Source: syllabus Science Class IX, Chapter 6, How Forces Affect Motion._
