ROLLING, TORQUE, and ANGULAR MOMENTUM
... p 4. We put p the origin at the position of the center of mass when the ball leaves the track (the “initial” position for this part of the problem) and take +x leftward and +y downward. The result of part (a) implies v0 = R = 6.3 m/s, and we see from the figure that (with these positive direction c ...

Force and Newton`s Laws
... Lubricant: A slippery substance used to reduce friction. Newton’s Second Law of motion: The acceleration of an object of a certain mass is determined by the size of the force acting and the direction in which it acts. ...

Chapter 10 – Rotation and Rolling
... Rotation axis: every point of a body moves in a circle whose center lies on the rotation axis. Every point moves through the same angle during a particular time interval. Reference line: fixed in the body, perpendicular to the rotation axis and rotating with the body. Angular position: the angle of ...

Rotational Motion
... In any closed system (including the universe) the quantity of angular momentum is fixed. Angular momentum can be transferred from one body to another but cannot be lost or gained. If a system has its angular momentum changed from the outside it is caused by a torque multiplied by time of impact. Tor ...

... If mass moves to the equator, it is further from the axis of rotation, so the rotational inertia of the earth increases. Because the angular momentum of the earth is conserved, this means its rotational speed decreases, i.e. the length of the day would be longer. ...

PHY203F08 Exam 3 Name
... 1. A bullet with a mass of 20.0 g and a speed of 960 m/s strikes a block of wood of mass 4.50 kg resting on a horizontal surface. The bullet gets embedded in the block. The speed of the block immediately after the collision A) cannot be found because we don't know whether the surface is frictionless ...
