Questions and Solutions

Question 1

Observe the pictures showing children pulling buckets from a well. Can you tell the difference between the two pictures? Which method would be easier – using the pulley or not using it to lift things?
Solution:

In the first picture, a child is shown trying to pull a bucket of water directly from the well using his hands. This requires a significant amount of effort. In the second picture, a pulley system is used. The child is pulling the rope, and the pulley helps to change the direction of the force and makes it easier to lift the bucket. Therefore, using the pulley is much easier than pulling the bucket directly without it.

Question 2

Look around your surroundings. Where all do you see the use of pulleys? List them.
Solution:

Pulleys are used in many places in our daily lives. Here are some examples:

  • To draw water from wells.
  • In elevators to move people and goods up and down.
  • On flagpoles to hoist national flags.
  • In construction sites to lift heavy building materials.
  • To open and close curtains in homes and theatres.
  • In cranes and bulldozers to lift and move heavy objects.
  • In some types of exercise equipment.

Note: Students' answers may vary based on their personal observations and experiences.

Question 3

With the help of a pulley, try and lift various things, as shown in the picture.
Solution:

This question encourages students to perform a practical activity. By using a pulley to lift different objects, students can directly observe how it makes the task easier. They can experiment with lifting light objects like a small bag of books or a water bottle, and heavier objects if available and safe to do so. This hands-on experience helps them understand the concept of mechanical advantage and the practical application of pulleys in a tangible way.

Common mistakes

  • Not recognizing the mechanical advantage provided by a pulley.
  • Failing to observe and list diverse applications of pulleys in their surroundings.

Revision tips

  • Focus on understanding why a pulley makes lifting easier.
  • Make a list of all the places you see pulleys in your daily life.
  • Try to explain the use of a pulley to a friend or family member.
