First, a single steel ball is rolled towards the magnet at a slow speed, as shown in step 1 at right. In step 2, the ball is attracted to the magnet more and more as it gets closer to it. The closer the ball gets, the stronger the attraction force. All this pull acting on the steel ball accelerates it to higher speeds. F = ma.

In order to examine the size effect of the steel ball on the friction coefficient of ice, steel balls of different diameters ranging from 1.6 to 12.7 mm were used as a slider. The experimental results obtained are shown in Figure 9, as an example, in which the friction coefficient μ k is plotted against the diameter R of a ball.

Initial: k = 1 2 mv 2 = 0 Final : k = 1 2 mv 2 = 1 2 (3 kg )(14 m /s)2 = 294 J So as the ball falls, its kinetic energy increases. It is the gravitational force that accelerates the ball, causing the speed to increase. The increase in speed also increases the kinetic energy. The process of a force changing the kinetic energy of an object is ...

where μ s is the coefficient of static friction and μ k is the coefficient of kinetic friction. The value of μ s is generally higher than the value of μ k for a given combination of materials.. Coefficients of friction between materials are best determined through testing. However, it is possible to find tables in the literature for friction coefficients between various materials.
