This resource, from the Association for Science Education (ASE) is a Key Stage Four investigation into kinetic and potential energy, based on a real-life context. If a large asteroid hit the Earth, could it cause a global catastrophe? In this unit, on a table-top scale, students simulate what an impact would be...

This simulation allows students to use an air hockey table to investigate simple collisions in 1D and more complex collisions in 2D. Students can experiment with the number of discs, masses, initial conditions, and can vary the elasticity and see how the total momentum and kinetic energy changes during collisions...

These diagnostic questions and response activities (contained in the zip file) support students in being able to:

• Predict that two substances in the gas state will react without mechanical mixing.
• Recognise that a successful collision between molecules is a collision where a new product...

This series of interactive excel sheets investigate models involving collisions.

The first sheet simulates two particles colliding. Initial velocity, mass and resulting velocity of the two particles can be set, or a...
