pushed away‚ or repelled‚ each other. The evidence showed that electric force made matter either attract or repel other matter. Electric force is caused by electric charge. Electric charge is a property of the bits of matter within atoms. Electric force can cause matter to attract or repel because there are two kinds of charge – positive and negative charge. The effects of electric force can be summarized as the law of electric charge: Pieces of matter with the same kind of charge repel

Our Electric Bicycle Project I have added an electric power assist onto a GT mountain bike. With a 3 HP peak motor‚ it is much more powerful than typical electric bicycles. The basic motivation to build an electric bike was to have a fun and efficient and environmentally friendly way to stay out my car for short trips around town‚ and also as a silent trail bike for exploring the hills. I wanted to get some exercise - this bike can still be pedaled. When I first put this together it was even more
