Physical Science






                  • Field lines show the size and direction of the force that is exerted on
                    another positively charged particle.

                  • Closely packed field lines show that the force is strong.
                  • The closer another object is to the charged particle (inside the field lines),
                    the greater the force of attraction or repulsion.

                  Charged particles in an object can give the object a positive or negative
                  charge, which can change how two objects affect each other.





                       Let’s Talk


                    Look at the following objects. Each object has an electric charge.



















                    1  What is an electric charge?

                    2  Which objects will attract each other?
                    3  Which objects will repel each other?

                    4  Why do the objects attract or repel each other?

                    5  Do the objects need to touch each other for a force to be exerted? Why or
                       why not?
                    Now complete the worksheet in the Workbook.





                       Let’s Reflect


                    1  Make a list of three facts about electric charge.

                    2  How do electrically charged objects affect each other?
