Quiz #4 Friction and Static electricity

Is a force that opposes motion (kinetic friction) between two surfaces that are in contact.

• friction

• motion

• rub

• energy

A surface like this offers:

• more friction

• equal friction

• little friction

• all of the above

A surface like this offers:

• little friction

• equal friction

• more friction

• all of the above

Friction in which two surfaces are not moving past each other.

• Rolling friction

• Static friction

• Kinetic friction

• Fluid friction

These are examples of:

• Static friction

• Rolling friction

• Fluid friction

• Kinetic friction

Friction in which two surfaces slide past one another.

• Fluid friction

• Rolling friction

• Static friction

• Kinetic friction

This is an example of:

• Rolling friction

• Static friction

• Kinetic friction

• Fluid friction

Occurs when an imbalance of charged particles collects on a surface, creating either an overall negative or positive charge.

• friction

• Static electricity

• motion

• force

Atoms have:

• electrons, protons and neutrons.

• balance, force and motion.

• matter, water and soil.

• oxygen, gas and dioxide.

This is an example of charging by:

• Induction

• Conduction
