What is the force that acts to resist motion between two surfaces?
Friction
Describe two ways to change the frictional force between two sold surfaces?
1 . By polishing the surfaces in contact 2 . By lubricating the surfaces in contact with oil or grease .
Is a force that resists motion between two surfaces that are in contact?
no
What is a force that opposes motion between two surfaces that are in contact .?
friction
What is the force called that opposes motion between two surfaces that are in contact?
Friction
What is the definition for friction?
a contact force that acts to resist sliding between two surfaces that are touching.

How can you decrease the friction between two surfaces?
Prevent them from coming into contact.
What is the force that opposed motion between two surfaces that are in contact?
Friction.

Is the rubbing force that acts against motion between two touching surfaces?
that is frictionfriction
What is the force called that opposes motion between two surfaces that are in contact?
Friction
What are the three properties of drag?
There are four main properties of friction. These include it being an electrostatic force between two surfaces, it acts parallel to the surfaces that are moving against each other, it is independent of the area of the surfaces in contact with one another, and it never initiates motion - it only responds to it.
What is the caused of friction between two surface contact?
1.Irregularities between the surfaces 2.Rusting
State laws of limiting friction?
1. the direction of force of friction is always opposite to the direction of motion.. 2. the magnitude of limiting friction depends upon the nature and state of polish of the two surfaces in contact and acts tangentially to the interface between them.. 3. the magnitude of limiting friction 'F' is directly proportional to normal reaction 'R' between the two surfaces in contact.. 4. the magnitude of limiting friction is independent of area and shape of surfaces in contact as long as the normal reaction remains the same..
