Other than gravity, the most commonly encountered force is what or the force that resists motion.

friction

the ratio of the force necessary to move an object (or keep it moving) and the normal force

coefficient of friction

friction between a solid and a liquid or gas

drag

a force that resists motion

friction

the force that presses two surfaces together and is directed perpendicular to the contact surface; on a level surface, its magnitude is equal to the force of the object's weight but in the opposite direction

normal force

force that opposes a rolling object

rolling friction

force that opposes a sliding object

sliding or kinetic friction

force that opposes the start of motion

starting or static friction

a force that develops when a mass is accelerated by gravity; stated as Fw = mg

weight

Friction is a force that resists what

motion

It occurs when a surface in motion rubs against another what

surface

What acts parallel to the surfaces that are moving against one another and in the direction opposite to the direction of the motion (represented by F).

Friction

riction is caused by the interaction of the what or what of each object sliding over each other.

atom or molecules

he more contact the atoms are able to make, the greater the what

frictional effect

A what surface will produce more friction (resistance) than a smooth surface

rough surface

The high points on one surface interact with the high points on the other surface allowing atoms and molecules to form temporary what

intermolecular bonds

The more bonds that are allowed to form, the greater the what

friction

he force that opposes the start of motion is referred to as what

starting or static friction

This force is caused by the what that form between two surfaces

tiny bonds

The pull required to keep the block moving at a constant speed in the example above is due to what

sliding or kinetic friction

What occurs as tiny intermolecular bonds are constantly being formed and broken.

Sliding friction

Sliding friction is also affected by the weight of the object and another force called the what

normal force

What is the force of the contact surface pressing opposite the weight of the object, as seen in the diagram below.

normal force

The normal force is always perpendicular to the what

contact surface

The ratio between the sliding friction and the perpendicular normal force is called the what of sliding friction

coefficient

What is represented by the Greek letter mu, μ,

coefficient

he third type of friction that can exist between solid surfaces is what or the force that opposes a rolling object

rolling friction

Friction can also exist between what

solids liquids and gases

Gases and liquids, such as air and water, offer what

resistance to motion

the opposing force between a solid and a liquid or gas

drag
