(Sweigart) NGSS Physics IS2T3: Coulomb's Law

Front

What is Coulomb's Law?

Back

Coulomb's Law describes the electrostatic force between two charged objects, stating that the force is directly proportional to the product of the magnitudes of the charges and inversely proportional to the square of the distance between them.

Front

What happens to the electrostatic force (F) as the distance (r) between two charges increases?

Back

The electrostatic force (F) decreases.

Front

What is the relationship between distance and electrostatic force?

Back

The relationship is inversely proportional; as distance increases, the electrostatic force decreases.

Front

What does it mean for two quantities to be inversely proportional?

Back

If one quantity increases, the other quantity decreases, and vice versa.

Front

What is the formula for Coulomb's Law?

Back

F = k * (|q1 * q2|) / r^2, where F is the force, k is Coulomb's constant, q1 and q2 are the charges, and r is the distance between the charges.

Front

What is Coulomb's constant (k)?

Back

Coulomb's constant (k) is a proportionality factor in Coulomb's Law, approximately equal to 8.99 x 10^9 N m²/C².

Front

If the distance between two charges is doubled, how does the force change?

Back

The force is reduced by a factor of 1/4.

Front

What happens to the electrostatic force if both charges are doubled?

Back

The electrostatic force increases by a factor of 4.

Front

What is the effect of increasing one charge while keeping the other constant?

Back

The electrostatic force increases.

Front

What is the significance of the sign of the charges in Coulomb's Law?

Back

Like charges repel each other, while opposite charges attract each other.
