Pulleys worksheets Grade 5

📚 Topic Summary

Pulleys are simple machines that use grooved wheels and a rope to lift objects. They change the direction of force, making it easier to lift heavy things. There are different types of pulleys, including fixed pulleys (where the pulley stays in one place) and movable pulleys (where the pulley moves with the object being lifted). Combining pulleys into systems can create even greater mechanical advantage!

🧠 Part A: Vocabulary

Match the term with the correct definition:

1. Term: Mechanical Advantage
2. Term: Pulley
3. Term: Fixed Pulley
4. Term: Movable Pulley
5. Term: Effort Force

1. Definition: A simple machine with a grooved wheel and a rope.
2. Definition: A pulley that remains in a fixed location.
3. Definition: A pulley that moves with the load.
4. Definition: The force applied to do work using a simple machine.
5. Definition: The number of times a machine multiplies the effort force.

(Match the numbers and letters. For example, 1-A if term 1 matches definition A)

✍️ Part B: Fill in the Blanks

A ______ pulley changes the direction of the ______ but does not reduce the amount of force needed. A ______ pulley reduces the amount of force needed to lift an object. The combination of fixed and movable pulleys is called a ______ system, which provides even greater ______ advantage.

💡 Part C: Critical Thinking

Imagine you need to lift a very heavy box to the second floor of your house. Describe how you could use a pulley system to make this task easier. What type of pulley system would you use, and why?
