This video introduces friction and drag, two contact forces. Friction and drag (also called air resistance or water resistance) can be explained with the particle model. These contact forces act ...between objects and can be both useful (like when a bike's tyres are gripping) or not so useful (like air resistance slowing you down).
Friction acts between two solids whereas drag acts between a solid and a fluid. We can reduce friction by lubricating the two objects which slightly separates them, allowing the two surfaces to glide more smoothly over each other. We can reduce drag by streamlining the solid object which reduces collisions with air or water particles, allowing the object to move more smoothly through the fluid.

This is a quick video walkthrough of an Edexcel exam question. It is designed so you can look at questions which relate to questions from specific parts of the course.
It ...is taken from a real paper and I have used a real mark scheme which I have adapted for on-screen use. If you listen carefully it will give you a really good idea of what an examiner is looking for.
