Charging

Front

What happens to a plastic strip when it is rubbed with cotton?

Back

The plastic strip loses electrons to the cotton and becomes positively charged.

Front

What is a conductor?

Back

A material through which electrons move easily.

Front

What charge does a neutral metal sphere acquire when touched by a negatively charged metal rod?

Back

The sphere becomes negatively charged.

Front

Why does a rubber rod become negatively charged when rubbed with fur?

Back

Molecules in the rubber rod have a stronger attraction for electrons than the molecules in the fur.

Front

What do like charges do?

Back

Like charges repel each other.

Front

What is the definition of charging by friction?

Back

Charging by friction occurs when two different materials are rubbed together, causing electrons to transfer from one material to another.

Front

What is an insulator?

Back

A material that does not allow electrons to move easily.

Front

What is the principle of conservation of charge?

Back

The total electric charge in an isolated system remains constant.

Front

What occurs during charging by conduction?

Back

Charging by conduction occurs when a charged object touches a neutral object, transferring charge.

Front

What is an example of a good conductor?

Back

Copper is an example of a good conductor.
