**Solve friction problems **

**In this activity the friction model F≤μR is used to solve two sets of problems. The first set consists of simple problems involving bodies in limiting equilibrium. Problems in the second set are more complex, and students solve these by combining the friction model with Newton’s Second Law and the constant acceleration equations.**

**Galileo's projectile model**

**A practical activity in which students analyse and validate Galileo’s model for the motion of a projectile. Students will need to be familiar with the uniform acceleration equations for motion in a straight line. **

**Vectors**

**Vectors**

**Basic manipulation of vectors in component form is reviewed, and then vectors are used to solve real-life two-dimensional problems. These involve the use of the uniform acceleration formulae and Newton’s Laws of Motion in vector form. **

**Investigating friction**

**A practical activity in which students investigate the relationship between the normal contact force and limiting friction. They should discover that friction is a variable force and its maximum value is proportional to the normal contact force.**

**Runaway train**

**Students collect data about a trolley rolling down a slope. They use this to simulate the motion of a train by fitting a quadratic curve to their data, using a graphic calculator or spreadsheet. The main emphasis of the activity is the modelling cycle.**
