Name Class Date An Improvised Accelerometer Objectives: 1. To create an improvised accelerometer. 2. To establish a general rule on determining the direction of the acceleration of an object based on the direction of its velocity. Materials: Cork plastic bottle pin thread stick Discussion: A cork accelerometer is a device that indicates the direction of the acceleration of an object. The direction of the movement of the cork represents the direction of the acceleration. It is not used to determine the magnitude of the acceleration. Procedure: 1. Attach a cork to a thread using a dressmaker’s pin. Using a short stick, secure the other end of the thread inside the cap of the plastic bottle. Fill the plastic bottle with water before replacing the cap. Invert the bottle. The cork should be able to move freely

Data: Movement Direction of Velocity Direction of Acceleration Speeding up to the right Speeding up to the left Slowing down to the right Slowing down to the left Moving at constant v to the right Moving at constant v to the left Questions: 1. What can be said about the direction of the acceleration of an object and the direction of its velocity when the object is speeding up? 2. What can be said about the direction of the acceleration of an object and the direction of its velocity when the object is slowing down? 3. What happens to the cork when the cart is moving at constant velocity? What does it mean?...

### 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.
