Year 7 & 8 TOC Force Drag & Friction LO: Investigating the effects of applying different forces to familiar objectDrag & Friction If you’ve ever seen a shiny floor, chances are you’ve tried to slide on it. So why is it that we can slide on smooth floor boards but not carpet?  The answer, has […]

13.1.4: Electrostatic forces

Year 7 & 8 TOC Force Electrostatic forces LO: Investigating the effects of applying different forces to familiar objectElectrostatic forces Electrostatic forces are seen when positive and negatively charged objects attract each other without having to directly touch each other. You can see this when you pick up a piece of paper or someone’s hair […]
