Friction can create big problems when it comes to how well moving things work and use energy.

• It changes useful moving energy (kinetic energy) into heat energy. This means we lose some of that energy.
• Because of this, things become less efficient and use more energy to do the same tasks.

To help with these friction problems, we can:

1. Reduce Friction: We can use things like oil or make surfaces smoother to cut down on resistance.
2. Increase Input Energy: We can add more energy to make up for the losses.

By dealing with friction, we can make energy transfer in systems work better.
