⚙️ Physics Made Simple: Understanding Levers! ⚙️
Levers are everywhere around us, helping us do work with less force! But how do you tell the three classes apart? The key is knowing what sits in the middle:
🔹 Class 1 Lever (L - F - E): The Fulcrum is in the middle.
Example: Scissors — the pivot point sits between where you squeeze and where it cuts.
🔹 Class 2 Lever (F - L - E): The Load is in the middle.
Example: Nutcracker — the nut (load) sits between the joint and your force.
🔹 Class 3 Lever (F - E - L): The Effort is in the middle.
Example: Tweezers — your fingers apply effort between the pivot and the item you're holding.
💡 Quick Memory Trick: 1-2-3 = F-L-E!
1st Class = Fulcrum middle
2nd Class = Load middle
3rd Class = Effort middle
