Newton`s Second Law
... Newton’s second law states that the acceleration of an object is directly related to the force on it, and inversely related to the mass of the object. You need more force to move or stop an object with a lot of mass (or inertia) than you need for an object with less mass. The formula for the sec ...

... 9. Find the moment of inertia (I) of two 5 kg bowling balls joined by a 1-meter long rod of negligible mass when rotated about the center of the rod. Compare this to the moment of inertia of the object when rotated about one of the masses. (The moment of inertia of each ball will be considered as mr ...

Circular Velocity and Centripetal Acceleration
... 25. A 0.56 kg plane attached to a 2.00 m string is rotated so that is makes 8.50 revolutions in one second. A. What must be the tension in the string? [3200 N] B. If the string's length is halved what does the tension become (same velocity as A)? [6400 N] C. If the plane rotates at 17 rev/sec (twice ...
