Writing a physics

Theory. Rolling motion involves that motions which combines translational and rotational motion of an object in respect to the surface. Whenever there is an ideal condition the two motions would be in contact with no sliding. In many cases, rolling is obtained by a speed of rotation at a point or line of contact that is normally equal to the speed of translation. In absence of sliding the motion of rolling is normally called pure rolling (Walker, 2010). This means that for a rolling object the mass centre moves by the translational motion, where as the other parts of the object, rotate around the centre mass. In practical experiments, the small deformations on the area of contact results into sliding. The resistance in rolling is lower than the friction due to sliding, hence rolling objects need minimal energy to be shifted than the sliding objects. In this respect, such objects move in an easier manner, whenever they go through some force due to a component along the surface (Adams, 2008). For example the existence of gravity on a surface that is tilted. Different from symmetrical objects, a cone’s rolling motion, happens in a manner such that during rolling, on a surface that is flat, the centre of gravity goes through a circular motion instead of a linear motion. The objects that roll may not only be axially symmetrical. The principle of rolling objects has been applied in the bearings of rolling elements like ball bearings in devices that are rotating. These objects are normally made of smooth metal substances, and the elements that roll encased in between the two rotating rings. In many processes, the ring in the inner part is normally linked to the stationery shaft. In this respect, as the inner ring remains stationery the outer ring remains free to allow movements having very minimal friction. This principle has been applied in motors. In many cases, the quantity of friction is depended on the parts mechanisms, ball bearings quality, and the amount of lubricants within the mechanism (Adams. 2008). Additionally, rolling objects are mostly used as transportation tools. One key way is through keeping the object on a number of rollers that are lined-up. The wheel objects are normally moved along a straight line, especially when the wheels are replaced continuously to the front.. For a rolling object, the particle velocity is normally given by; Velocity = r x w.................... ...Show more

Summary

The prime purpose of this experiment was to utilize the cumulative knowledge of physics in performing an experiment without any help from the computer, to measure time and calculate the velocity of a rolling object, and to predict the velocity of a rolling object…

This indicates that the resistance of a wire is directly proportional to the length of the wire. As length increases, the resistance of the wire increases in equal proportion. Therefore, if the wire D is double in length, all other factors remaining the same, its resistance will be double.
