🔧 Work and Effort
This quiz introduces Grade 2 students to the concept of work in physics—when a force is applied to move something over a distance. Discover how simple machines like ramps, levers, and pulleys help reduce the effort needed to do the same work. Through real-world examples like lifting boxes, moving furniture, and opening doors, you'll learn how tools make tasks easier and why they're so useful. **What you'll learn:** - Define work as force applied over distance - Understand effort and how machines reduce it - Recognize examples of simple machines in daily life - Explain why tools and machines help us work more efficiently
