PPT-Electric Charge, Force,

and Energy 2014 Pearson Education Inc What s new in this chapter What is the interaction responsible for holding the particles together is the same interaction that makes the toner stick to a copier drum and a balloon stick to your hair as well as many other phenomena that we observe in our everyday world. How do you find the area of a triangle?. This was the most missed question on the test…. DO WORK. STOP. Objectives.

Charges are conserved. Charges are additive in nature. Charges are quantised.. PROPERTIES OF ELECTRIC CHARGES. PRODUCTION OF ELECTRIC CHARGE. We can get electric charge by three ways. By friction or rubbing.
