CIF Review

The direct transfer of electrical energy from one object to another that it is touching

• Conduction

• Mass

• Induction

The transfer of charge without contact between materials is Induction

• true

• False

Ms Pippin rubbed two balloons with a piece of wool. What will happen when the balloons are brought near each other?

• The balloons will repel each other.

• The balloons will attract each other.

• The balloons will become positively (+) charged.

• The balloons will pop.

If a substance has a higher number of electrons than protons on its surface, what type of charge does it have?

• A positive charge.
• A negative charge.
• A neutral charge
• No charge at all

During a lab a balloon was rubbed with a wooly fabric. This is an example of which type of charging?

• conduction

• friction

• induction

What types of charges attract?

• Positive and Positive
• Positive and Neutral
• Negative and Neutral
• Positive and Negative

An object that is neutral contains the same number of electrons and protons.

• True

• False

the charging of an object by the contact of a charged object to a neutral object (like touching a door knob)

• induction

• conduction

• friction

A student is planning an investigation to determine the relationship between magnetism and the movement of electrical charge in a circuit. A diagram of the circuit is shown.

The student is planning to make changes to the circuit to see how the changes will affect the number of paper clips that are picked up by the electromagnet. What is the likely effect of the magnetic field if the student adds more coils?

• increase

• decrease

• no change
