Types of Interactions PS2.B: Types of Interactions in contact exert forces on each other. (3-PS2-1) and magnetic forces between a pair of objects do not require that the objects be in contact. sizes of the forces in each situation depend on the properties of the objects and their distances apart and, for forces between two magnets, on their orientation relative to each other. (box of reams of copy paper and box of lightly waded single sheets of paper) identical distances. Discuss the amount of force needed to move the objects. Use a bulb, battery, and wire system to test objects for conductivity. Observe the materials contained inside of a light bulb and diagram the flow of electricity that lights the bulb. Add objects to a bulb, battery, and wire system to test to see if objects are conductors or insulators of electricity. Add switches to a closed circuit. Add more batteries to a simple bulb, battery, and wire system. Observe the effect of additional energy in the system. Observe and describe 3-PS2-3.
