U5 Day 3 Warm up - Conduction, Induction, Friction

Front

What method charges a conductor when a negatively charged rod touches it?

Back

Conduction

Front

What happens to the number of electrons in a negatively charged material?

Back

It has gained electrons.

Front

What causes static electricity?

Back

A buildup of charges on an object.

Front

How does a balloon acquire its overall charge?

Back

It gains electrons.

Front

What is the charge on a t-shirt if it has a +3 charge?

Back

+3

Front

Define conduction in the context of electricity.

Back

Conduction is the process by which electric charge is transferred through direct contact between materials.

Front

What is the role of electrons in static electricity?

Back

Electrons are the negatively charged particles that can build up on an object, leading to static electricity.

Front

What is the difference between conduction and induction?

Back

Conduction involves direct contact transfer of charge, while induction involves the rearrangement of charges in an object without direct contact.

Front

What is the significance of a negatively charged object?

Back

A negatively charged object has an excess of electrons.

Front

How can you determine if an object is positively or negatively charged?

Back

By observing the behavior of the object with other charged objects; like charges repel, opposite charges attract.
