Electric Charge and Forces Concepts

What type of force causes a sock to stick to a shirt even when they are not touching?

• Magnetic force

• Gravitational force

• Electric force

• Friction force

What property of matter is responsible for electric forces?

• Mass

• Volume

• Electric charge

• Temperature

Which of these is NOT a type of electric charge mentioned?

• Positive

• Negative

• Neutral

• Magnetic

What does it mean for an object to have a neutral electric charge?

• It has only positive charges

• It has only negative charges

• It has an equal amount of positive and negative charges

• It has no charges at all

How do objects like a shirt and sock become electrically charged in a dryer?

• By getting hotter

• By moving around a lot

• By exchanging negative charges

• By changing their color

What happens when two objects have opposite electric charges?

• They repel each other

• They attract each other

• Nothing happens

• They become neutral

What happens when two objects have the same type of electric charge?

• They attract each other

• They repel each other

• They become neutral

• They stick together

If a sock and a shirt are attracted to each other after being in a dryer, what must be true about their electric charges?

• They must both be positive

• They must both be negative

• They must have opposite charges

• They must both be neutral

How does the amount of electric charge on objects affect the strength of the electric force between them?

• More charge means weaker force

• More charge means stronger force

• Charge has no effect on force

• Only positive charges create force

What happens to the electric force between two charged objects if you move them farther apart?

• The force gets stronger

• The force gets weaker

• The force stays the same

• The objects will always attract
