How does friction affect the energy of moving objects?

• It increases kinetic energy

• It converts kinetic energy into thermal energy

• It creates potential energy

• It has no effect on energy

In an experiment, if you slide the same object over both a rough and a smooth surface, which surface will likely show a quicker stop of the object?

• The smooth surface

• The rough surface

• Both will stop at the same time

• It depends on the weight of the object
