Unit 6 "Non-Contact Forces" Review Practice

Front

What happens to the amount of force as the distance between two charged objects decreases?

Back

The amount of force increases.

Front

Which factor does NOT affect the strength or direction of an electrical force?

Back

The mass of the objects.

Front

Which object has the greatest charge magnitude? - An object with a charge of 0, -2, -3, or +2?

Back

An object with a charge of -3.

Front

What happens to the amount of force as the distance between two charged objects increases?

Back

The amount of force decreases.

Front

True or False: Bar magnets are temporary.

Back

False.

Front

Define non-contact forces.

Back

Forces that act on an object without physical contact, such as gravitational, magnetic, and electrical forces.

Front

What is the relationship between charge magnitude and electrical force?

Back

Greater charge magnitudes result in stronger electrical forces.

Front

Explain how distance affects electrical force between charged objects.

Back

As the distance increases, the electrical force decreases; as the distance decreases, the electrical force increases.

Front

What are the two types of electric charges?

Back

Positive and negative.

Front

What is the principle of superposition in the context of electric forces?

Back

The total force acting on a charge is the vector sum of all individual forces acting on it.
