Problem: 1. A particle traveling around a circle at constant speed will experience an acceleration. True or False2. The test-mass is referred to as m and it hangs from the test-mass riser. True or False3. A particle travels 17 times around a 15-cm radius circle in 30 seconds. What is the average speed (in m/s) of the particle?4. What measurements will be made to determine the magnitude of the test-mass centripetal acceleration?(1) The mass of the test-mass.(2) The velocity of the test-mass.(3) The radius of the circular path.(4) The mass of the hanging mass.(5) The spring constant.(6) The period of the orbital motion.5. Before rotating the platform, the hanging mass is disconnected from the test mass and removed from the platform. . True or False6. A particle in uniform circular motion requires a net force acting in what direction?7. The centripetal force acting on a particle is given by F = mv2/r. If the centripetal force and mass are kept constant, increasing the radius of the particle's circular path will mean that the particle's velocity must increase. True or False

1.

Objects following a circular path at a constant speed experience centripetal acceleration. The acceleration is due to the change in the direction of the velocity.
