(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

F decreases.

Front

When are electric forces strongest between charges?

Back

Electric forces are strongest when charges are close together.

Front

What is the relationship between electrostatic force and the magnitudes of the charges (q1 and q2)?

Back

Electrostatic force F is directly proportional to both q1 and q2.

Front

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

Back

The force is reduced by 1/4.

Front

What type of relationship exists between distance and electrostatic force?

Back

The relationship is inversely proportional.

Front

Define 'inversely proportional' in the context of electrostatic force and distance.

Back

Inversely proportional means that as one quantity increases, the other quantity decreases.

Front

What is the formula for calculating the electrostatic force between two charges?

Back

F = k * (|q1 * q2|) / r^2, where k is Coulomb's constant.

Front

What does the variable 'k' represent in Coulomb's Law?

Back

'k' is Coulomb's constant, which quantifies the electrostatic force in a vacuum.

Front

What happens to the electrostatic force if one of the charges is doubled?

Back

The electrostatic force will also double.
