TOPIC 10.1 Electric Charge and Electric Force

Front

What is charge?

Back

Charge is a fundamental property of all matter.

Front

How is charge described?

Back

Charge is described as positive or negative.

Front

What is the elementary charge?

Back

The magnitude of the charge of a single electron or proton, the elementary charge e, can be considered to be the smallest indivisible amount of charge.

Front

What are the charges of an electron, proton, and neutron?

Back

The charge of an electron is −e, the charge of a proton is +e, and a neutron has no electric charge.

Front

What is a point charge?

Back

A point charge is a model in which the physical size of a charged object or system is negligible in the context of the situation being analyzed.

Front

What does Coulomb’s law describe?

Back

Coulomb’s law describes the electrostatic force between two charged objects as directly proportional to the magnitude of each of the charges and inversely proportional to the square of the distance between the objects.

Front

What is tangential acceleration?

Back

Tangential acceleration is the rate at which an object’s speed changes and is directed tangent to the object’s circular path.

Front

What is the net acceleration of an object moving in a circle?

Back

The net acceleration of an object moving in a circle is the vector sum of the centripetal acceleration and tangential acceleration.

Front

What is uniform circular motion?

Back

The revolution of an object traveling in a circular path at a constant speed can be described using period and frequency.

Front

What is defined as period, T?

Back

The time to complete one full circular path, one full rotation, or a full cycle of oscillatory motion is defined as period, T.
