Consider the car and the tissue box being two separate objects, both travelling at the same velocity. If one of them is forced to a stop (in this case, the car), then the tissue box (not having anything to stop it) will continue on a straight path, following the direction it was going in. A similar example of such a principle would be a person going down a hill on a skateboard, if the skateboard is suddenly forced to stop, then the person will be sent forward, because <u>an object in motion tends to stay in motion</u>.
An atom with a greater number of protons than electrons will be positively charged. An atom with a a greater number of electrons will be negatively charged.
