⚙️ Simple Machines: Wheels and Ramps
Learn about two important simple machines that help us do work every day! Wheels reduce friction and make rolling motion smooth, while ramps help us move heavy objects upward with less effort. Discover how these tools change the direction of force and make tasks easier. **What you'll learn:** - How wheels reduce friction and enable smooth rolling motion - How ramps reduce the effort needed to move objects upward - Why simple machines help us do work with less force - Real-world examples of wheels and ramps in action
