7k forces
You will learn about the different forces that can act in an objet and what happens if they are unbalanced or balanced. You will be able to calculate speed and weight as well as draw and interpret distance time graphs.

Here are the learning objectives for this topic I can o Measure force using a Newton Meter o Calculate density o Predict if an object will float or sink o Predict what will happen if forces are balanced or unbalanced o Draw diagrams to show forces acting o Calculate weight o Calculate speed o Interpret a distance time graph I understand o that forces are measured in Newtons o that forces can be either contact or non-contact o that weight always acts downward o why some objects float and others sink o why some objects are more or less dense o that upthrust pushes upwards on objects in water o that the upthrust produced by salty water is different to fresh water o that friction opposes motion and can act in water and air as well as solids (called water and air resistance) o how friction is reduced o why friction can be useful o that weight is a combination of mass and gravity o that there are many different units for speed o how speed affects stopping distance of a car |

BBC Bitessize. Here is the revision part.
Bitesize activity. All about forces, has some Year 8 and Year 9 info. Bitesize quiz. It also has some Year 8 and 9 information. Try this animation to label the forces in the playground. Play games with this excellent website that looks at forces in the olympics. |
