Non-conservative forces are important in energy systems. They come into play when energy isn’t just moved or kept neatly. Here are some examples where these forces really show their effects:
Friction: Imagine sliding a book across a table. When you push the book, not all the energy you use goes into moving it. Some energy gets lost as heat because of friction. This means the energy used to move becomes thermal energy, which affects how we think about saving energy.
Air Resistance: When you ride a bike or throw a ball, air resistance works against you. It slows you down. This force takes some kinetic energy (the energy of movement) and turns it into thermal energy. So, we end up with less total energy than we started with.
Inelastic Collisions: When two things crash into each other and stick together, some of their moving energy is changed into sound, heat, or bent shapes. A car crash is a good example of this. You can see how energy is lost and not fully kept within the system.
In all these situations, non-conservative forces show us that energy doesn’t always stay the same. It can change forms, which can make it harder to keep track of energy conservation!
