Experiments/practicals involving motion?

[Voltman]

Hey, does anyone know of any good practicals that can be done for physics at school, particularly something involving motion?

Here are some pretty basic ideas:

+Anything using energy conservation (looking at the efficiency of an energy transfer in a collision, for example.. with basketballs, running shoes)
+Elastic properties of substances at different temperatures
+Air resistance and terminal velocity
+Testing Newton's 3 Laws (and the kinematics laws)
+Rolling carts (one with wheels, one without) down inclines (choose a surface with little friction, such as ice) and comparing the final velocity (pretty easy to predict, but you may as well test it)
+Releasing a mass attached to a spring and observing the point at which the mass moves with the greatest velocity (also relatively easy to predict, but the potential for great experimental error)

Pendulum is pretty interesting, but you have to make approximations.
