Electricity always wants to travel to the path of least resistance, which is usually through conductive materials. It seeks to complete a circuit to flow from the source to the destination.
It could mean that he's interested in you romantically or sexually. However, it's important to communicate openly with him to understand his intentions and set boundaries that you're comfortable with.
Yes, friction acts in the opposite direction that an object wants to slide. It opposes the relative motion between the surfaces.
Static electricity can be either positive or negative, depending on the excess or deficiency of electrons on an object. If an object has an excess of electrons, it will have a negative static charge, and if it has a deficiency of electrons, it will have a positive static charge.
Extending a rubber band allows it to store more potential energy, which can provide a greater force to slow down the jumper during bungee jumping. This can lead to a smoother and more controlled descent. However, if the rubber band is extended too much, it may lose its elasticity and not provide enough resistance to safely decelerate the jumper.
