As a result of the work done by this friction, the kinetic energy of the disk decreases. This is shown in the initial stage of the animation shown below. As the disk continues to roll with slipping, ...

For example, when a bike applies its brakes and slows down the kinetic energy of the bike is transformed ... This is called the Work Done against Friction (\(E_{w}\)). Travelling between stops ...

When friction acts between two surfaces that are moving over each other, some kinetic energy is transformed into heat energy. Friction can sometimes be useful. For example, we rely on the soles of ...
