Worked practice questions

A boy shoves a trolley forward. In science, that push or pull on an object is called a:

  1. Force
  2. Focus
  3. Flash
  4. Flare
Show answer and solution

Correct answer: A. Force

1. A shove is a push applied to the trolley. 2. Science gives every push or pull one name. 3. That name is force. _Source: syllabus Science Class VIII, Chapter 8, Force and Pressure._

Two children push the same box in the same direction. The two forces on the box:

  1. Angle out
  2. Add up
  3. Add zero
  4. Ask twice
Show answer and solution

Correct answer: B. Add up

1. Both pushes point the same way. 2. Nothing cancels between them. 3. So the forces add up to a bigger push. _Source: syllabus Science Class VIII, Chapter 8, Force and Pressure._

Two teams pull a rope equally hard in opposite directions. The rope therefore:

  1. Stays put
  2. Snaps back
  3. Speeds up
  4. Spins out
Show answer and solution

Correct answer: A. Stays put

1. Equal pulls point opposite ways. 2. The net force works out to zero. 3. So the rope stays put. _Source: syllabus Science Class VIII, Chapter 8, Force and Pressure._
