About this app
An interactive science learning app that demonstrates how levers and pulleys change the force needed to lift a load. Move the fulcrum, adjust the load weight, switch among fixed, movable, and combined pulleys, and pull the rope to observe changes in force, distance, and lifting height. A challenge section tests learners on calculating the required force from illustrated conditions.
Use cases
- Elementary students learning about simple machines
- Teachers demonstrating force and mechanical advantage in class
- Parents guiding hands-on science practice at home
- Learners reviewing lever and pulley concepts through quizzes
Features
- Interactive fulcrum slider with adjustable load weight
- Force comparison bars for load weight and required force
- Fixed, movable, and combined pulley modes
- Rope-pulling control showing pulled distance and lifting height
- Challenge questions with answer choices, score, and streak tracking
