Physics Interim Review

Which particles make up an atom? (pick more than one!)

• positrons (+)

• electrons (-)

• neutrons (0)

• protons (+)

• neutrons (-)

When a charge is transferred to an insulator...

• the charge will spread throughout the object

• the charge will remain at the location it was transferred

• the charge will dissipate

When a charge is transferred to an conductor...

• the charge will spread throughout the object

• the charge will remain at the location it was transferred

• the charge will dissipate

Objects become negatively charged by:

• losing protons

• gaining electrons

• gaining neutrons

• losing electrons

Objects become positively charged by:

• losing protons

• gaining electrons

• gaining neutrons

• losing electrons

Attracting a soda can with a charged balloon is charge by:

• friction

• conduction

• induction

• transduction

Gaining a static charge by rubbing your feet on the carpet is charge by...

• friction

• induction

• conduction

• tranduction

A student touches a charged rod to a metal plate. This results in charge by...

• friction

• induction

• conduction

• transduction

Opposite charges:

• repel

• attract

• do not interact

• repel or attract depending on the mass of the charges

Like charges:

• repel

• attract

• do not interact

• repel or attract depending on the mass of the charges
