Electric Forces Grade 3

What is an electric force?

• The force that exists between charged particles.

• The force that exists between gravitational particles.

• The force that exists between neutral particles.

• The force that exists between magnetic particles.

What are positive electric forces?

• Forces that have no effect on charged objects

• Forces that attract or repel positively charged objects

• Forces that only attract positively charged objects

• Forces that attract or repel negatively charged objects

What are negative electric forces?

• Forces that only attract charged particles

• Forces that only repel charged particles

• Forces that attract or repel charged particles

• Forces that have no effect on charged particles

Do positive and negative electric forces attract or repel each other?

• repel

• neutralize

• attract

• cancel out

Give an example of a positive electric force.

• Attraction between two negatively charged objects

• Attraction between a positively charged object and a negatively charged object

• Repulsion between two positively charged objects

• Repulsion between a positively charged object and a negatively charged object

Give an example of a negative electric force.

• Attraction between two negatively charged objects

• Attraction between a positively charged object and a negatively charged object

• Repulsion between a positively charged object and a negatively charged object

• Repulsion between two negatively charged objects

What happens when two positive electric forces interact?

• They cancel each other out.

• They create a neutral charge.

• They repel each other.

What happens when a positive and a negative electric force interact?

• They cancel each other out.

• They attract each other.

• They repel each other.

• They create a neutral charge.

How can electric forces be used in everyday life?

• Electric forces have no practical applications in everyday life.

• Electric forces can only be used in scientific experiments.

• Electric forces are only used in specialized industries and not in everyday life.

• Electric forces can be used in everyday life in various ways.
