Question

1. An object slows down due to friction. What does the energy lost by the object go?
2. Can the amount of kinetic energy of a system of objects change?
3. Can the work done by a kinetic friction force ever be positive? 1. An object slows down due to friction. What does the energy lost by the object go?

Explanation / Answer

1.) when object slow down due to friction, then, its kinetic energy losses. this lose of kinetic energy is gone to heat and electromagnetic wave.

2.) yes, amount of kinetic energy of the system can be changed by changing the magnitude of the velocity or by changing the mass of the system of the particle.

3.) work done by kinetic friction never be positive,

but static friction does positive work when object roll without slipping.
