If the block is at rest, we say that the force of static friction, Fs is acting to counterbalance the weight component in the x-direction, and the coefficient of friction is that Simulator. Ramps are used in many scenarios, and are used to make work against gravity easier (since the force decreases). UTC Physics 1030L: Friction, Work, and the Inclined Plane 40 The magnitude of the frictional force, Ff, on an object, can also be described by: Ff = μN (eq. 2. Work done on a ball rolling in a spiral path along the inside of a hollow cylinder. 3.1. What is the work done against friction before the body comes to rest? By Steven Holzner .

If you change your frame of reference to the non inertial frame of the inclined plane (although it won't help you solve this question using W.E.T. Would the speed of the ball be increased or decreased if air resistance were taken into account. So distance is 500 meters. To review, the process for solving inclined plane problems is as follows: Draw a sketch of the problem. The speed of the ball would be decreased when it hit the ground if air resistance Motion of an object sliding down an inclined plane. s$^{-1}$}\) in a vacuum.
