Experiments for physics of traffic
Experiments for physics of traffic (Breaking distance)
Although most curricula do not include velocity as a topic for secondary
degree 1, this item is handled systematically in nearly all school books.
Students often have no exact perception of velocity. Being necessary for
mechanics, it is worth to make it to a subject of discussion. Physic lessons
can be a contribution to recognize the danger of road traffic.
By sensitising it will be better possible to evaluate the consequences
of own behaviour. If students observe the stopping distance in
experiments under different circumstances, a conceptual framework will
arise, which enables to see and rate perils. Own experience serve as basis.
Therefore the aim of this experiment is measuring velocity and the explication
of stopping distance and velocity.
