Q:
# What is frictional force?

A:
### Quick Answer

**Frictional force is the force created by two surfaces contacting and sliding against each other.** There several different forms of frictional forces, such as dry friction and fluid friction.

Frictional forces are affected by the texture of the surfaces and the amount of force pushing them together. The angle and position of the objects affects the amount of frictional force. If an object is sitting flat against an object, then the frictional force is equal to the object's weight. If the object is pushed against the surface, the frictional force is increased and becomes greater than the object's weight. Objects pulled away from the surface and those at an incline with the surface have less frictional resistance.

Q:
## How do you measure angles?

A:Use a protractor to measure the number of degrees in an angle. Place the protractor over the angle so that one line goes along the protractor's zero degrees line, the vertex is at the center of the zero degrees line, and the second line passes through another number on the protractor.

Q:
## What is a linear pair?

A:

Full Answer >**A linear pair is a geometric term for two intersecting lines with a 180-degree angle.**It is also known as a conjecture, or hypothesis, of linear pairs. Linear pairs require unshared sides of the angles to create rays on opposite sides.Filed Under: -
Q:
## What is a golden spiral?

A:A golden spiral is a spiral that grows according to the golden ratio, which is approximately 1.618. In a golden spiral, each quarter turn causes the spiral to grow by a factor of 1.618.
