  1. Forces and motion

    Slide 1 - Forces and motion

  2. Use the equation v=d/t

    Slide 2 - Use the equation v=d/t

  3. Use the equation v=d/t – but rearrange it

    Slide 3 - Use the equation v=d/t – but rearrange it

  4. Forces

    Slide 4 - Forces

    • Remember, there are 4 main forces you need to know
  5. Forces		Write this note into your book

    Slide 5 - Forces Write this note into your book

    • Forces change an objects motion.
    • When a force is applied to an object, the object will change direction or speed. We describe this as the forces being unbalanced
    • If the forces are BALANCED, they cancel each other out, and the object will not change speed or direction
  6. Friction/Drag	Write this into your book

    Slide 6 - Friction/Drag Write this into your book

    • Friction occurs when two objects rub together and acts to stop a force.
    • Drag is friction cause by gases (like the air) or liquid (like water in a swimming pool)
    • Both friction and drag act to slow you down.
    • But they can also be helpful – friction helps to keep a cars tyres on the road
  7. A video explaining balanced and unbalanced forces

    Slide 7 - A video explaining balanced and unbalanced forces

  8. Use the following animation to explore how forces interact with each other – just link on the pictures to complete each one 

  9. Size matters

    Slide 9 - Size matters

    • You need to be careful when drawing the force arrows on diagrams
    • The size of the arrows indicates the size of the force
  10. Next steps

    Slide 10 - Next steps

    • You should have already completed page 100 and 101 in your Scipad, if you haven’t, do this now
    • Then complete page 102 and 103
    • All done – you can either check out the revision questions on page 122 and 123, or look through some of the links on the ultranet page
