Static Charge

• Objects that are charged can affect other charged particles using the non-contact force of static electricity.
• When insulating materials rub against each other they may become electrically charged.
• Electrons may be ‘rubbed off’ one material and on to the other.

  The material that gains electrons becomes negatively charged. The material that loses electrons is left with a positive charge.
• Friction causes electrons to gain energy. If they gain enough energy they leave the atom and ‘rub off’ onto the other material.
