collisions
What collisions means in Physics GCSE, as defined for AQA.
Definitions of collisions
Exam boards and our study guides word this term in slightly different ways. Learn the version your board uses.
Check what you remember
Read the wording for your board, then hide it and explain collisions in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: AQA
When a moving object hits an obstacle, its kinetic store empties, mostly into thermal stores, with some energy transferred by sound waves.
Events in which objects interact, and momentum can be described and explained using the concept of momentum as a model.
