This week in physics, we learned about electric charges and forces. This means that there are differing amounts of electrons and such in a given particle, which makes up its charge. Positively charged things will naturally attract to negatively charged things, bringing them together. These particles will stick and hold together, and be hard to force apart. One such example is the picture above, which shows some magnets on my fridge. These magnets are attracted to the fridge through a charge, which makes them stick.
