I have written this activity to use no electronic technology, other than a calculator. A calculator will be fine. It uses a ramp to accelerate a sphere up to launch speed, and then hurls the sphere off the edge of a flat table. The goal is to predict, using physics, where the ball will land with respect to the edge of the table.
If you have tech, such as motion sensors or photogates, that you'd like to use on it, it will still be an excellent activity.
You can also break this into pieces for uses over multiple units: Conservation of energy activity, Work and energy activity, Energy lost to friction, Conservation of momentum in 2D, and on and on.
As with my other activities there is a "for the teacher" page with things to look for during the activity, or modifications you can make.
