Front

What is the relationship between the strength of magnetism and the distance between two objects?

Back

The strength of magnetism has an inverse-square relationship with the distance between two objects.

Front

What is direct current?

Back

Direct current (DC) is an electric current that flows in one direction.

Front

What does electrical force depend upon?

Back

Electrical force is based upon charge.

Front

What does gravitational force depend upon?

Back

Gravitational force depends upon mass.

Front

What is potential difference?

Back

Potential difference is the difference between the electric potential of any two charges in an electrical system; expressed in volts, it is responsible for the flow of electricity in a system.

Front

What is electrical potential energy?

Back

Electrical potential energy is the amount of energy that acts upon a charge in a particular field.

Front

What is the unit of potential difference?

Back

The unit of potential difference is volts.

Front

What is the difference between alternating current and direct current?

Back

Alternating current (AC) changes direction periodically, while direct current (DC) flows in one direction.

Front

What is the formula for calculating electrical potential energy?

Back

Electrical potential energy (U) can be calculated using the formula U = qV, where q is the charge and V is the potential difference.

Front

What is the significance of the inverse-square law in physics?

Back

The inverse-square law states that a physical quantity is inversely proportional to the square of the distance from the source, applicable in gravity, magnetism, and electrostatics.
