Lab 9: Centripetal Acceleration 10/28/20 Student Name: Logan Xu REPORT Section Number: 31 Instructions 1) Follow all of the lab activity steps given in the Lab Procedure. 2) TYPE YOUR ANSWERS IN THE PROVIDED SPACES below & in your data tables. 3) Show all of your calculations performed . Save as .PDF and submit. Results 1) Did your data display the expected relationship between the centripetal force and angular speed of the rotation? What evidence do you have of this? What changed when you changed either the mass or radius? Write out your answer in a clear and well supported paragraph. Because of the formula F = m*(w^2) * r, a = V^2/r ; V = w*r; F is proportional to mass, radius, square of angular velocity. When we decrease either the mass or radius, both the force and angular speed will decrease as well. 2) When the value of the revolving mass and the radius of its path are both held constant, what theoretical effect on the period does increasing the radial force have? Did you observe this experimentally? Write out your answer in a clear and well supported paragraph.
