... Why Isn’t Work Done On The Bucket of Water? • Work is only done when COMPONENTS of a force are parallel to a displacement. • Since Kim exerts an upward force on the bucket of water, which is perpendicular to the displacement, there is no work done on the bucket of water. ...

... 18*. A coin with a diameter of 2.4cm is dropped onto a horizontal surface. The coin starts out with an initial angular speed of 18rad/s and rolls in a straight line without slipping. If the rotation slows with an angular acceleration of magnitude 1.9rad/s2, how far does the coin roll before coming t ...

... 5. The property is called inertia. 6. Weight depends on gravity, while mass does not. 7. Your weight would be greater on the Earth because of its stronger force of gravity. Mass, however, is the same everywhere. 8. Newtons for weight; kilograms for mass. 9. One kg would weigh less on the Moon. 10. N ...

Rotational Motion: Moment of Inertia
... where r is the lever arm, F is the force and θ is the angle between the force and the lever arm. In this lab the lever arm, r, will be the radius at which the force is applied (i.e. the radius of the axle). The force will be applied tangentially (i.e. perpendicular) to the radius so θ is 90◦ and sin ...
