# Problem: 1. A particle traveling around a circle at constant speed will experience an acceleration. 2. The test-mass is referred to as m and it hangs from the test-mass riser. 3. 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.6. 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.

1. Acceleration occurs if the direction or magnitude of the speed of an object changes.

The direction of the speed of an object going around a circle keeps on changing and is always directed to the tangent of its position.
