Factors that Affect Friction
Gravity
Vectors and Pressure
100
Push or a pull
What is Force?
100
Opposes the motion of an object
What is friction?
100
This happens when you speed up rubbing your hands together.
What is increased friction?
100
This person came up with the idea of gravity.
Who is Sir Isaac Newton?
100
This measures the amount of force applied to a certain surface area
What is pressure?
200
Equal in size, opposite in direction
What is balanced forces
200
Two surfaces moving past each other
What is sliding friction?
200
Besides rolling friction, sliding friction can be overcome by increasing the _________________ to move the object
What is force?
200
This force pulls objects toward each other
What is gravity?
200
A force of 55 N is moving East and an opposite force of 30 N is moving. The resultant force is
What is 25N East?
300
Causes objects to change motion
What is unbalanced forces
300
Stationary
What is static friction?
300
The rougher this is, the more friction
What is texture?
300
The bigger this is the more gravitational pull
What is mass?
300
The surface area of an object is increased. The pressure
What is decreased?
400
Unit of measurement for force
What is a Newton?
400
Reduces sliding friction with wheels.
What is rolling friction?
400
Besides slowing an object down, friction causes this to happen.
What is heat?
400
This causes less gravitational pull
What is less more and more distance?
400
Two ways in which pressure can be changed
What is change the force or the area?
500
Equipment used to measure force
What is a spring scale?
500
This friction slows objects down as they fall?
What is fluid friction?
500
These are four factors that affect friction
What is speed, texture, mass, force, surface area, thickness
500
Besides gravity, this other force acts on objects as they fall
What is air resistance?
500
Two forces are moving each at 50N South. An opposite force is moving 100N North. The resultant force is
What is 0N?
