Physics 123 – Minilab 2 FREE FALL Names _____________________ ________________________ Objective In this week’s lab you will use the ultrasonic ranger to measure the position, velocity, and acceleration of a bouncing ball. (See example 2.7 on p. 55 of your textbook.) Discussion In last week’s lab you found it was rather difficult to produce a constant velocity or acceleration by moving a cart towards or away from the sensor. This week’s lab will explore a situation for which the acceleration is constant: a freely falling object. If air resistance is negligible, a bouncing ball is falling freely when it is not in contact with the floor. Its position y as a function of time is then given by 2 2 1 gt t v y y - = . During free fall the ball’s velocity is given by gt v t v y y - = 0 ) ( , and is thus a linear function of time. Procedure The motion sensor is suspended high above the floor. Drop the ball and let it bounce three times within the range of the sensor. Record this motion with the sensor and the Logger program. It may take several tries to get a good plot of three bounces.

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
