How important is momentum? Pupils investigate and apply the definition of momentum as they conduct analyses during a series of one-dimensional collisions. They infer the relative masses of two objects by carefully staging and predicting what will occur as each collision takes place and conclude with a discussion on the general topic of collisions.
