This activity is designed for pre-AP or Honors level physics at the beginning of the unit on momentum and impulse.
Students measure the average speed of a golf ball rolling down a gentle incline and across a table and calculate the momentum. They then allow the golf ball to hit a second stationary golf ball at the bottom of the ramp and measure the average velocity of each of the balls, then calculate the total momentum after the collision.
This is a simple activity, without technology more complex than a stopwatch, but this product includes a separate version so you can also use a slo-mo app like Technique.
It's an opportunity for students to recognize that energy is lost to friction in the interaction and to do basic momentum calculations. The values are very small and yet very significant.
