SIMPLE BASIC MACHINES
LEVERS
Inclined Plane
Force and Work GENERAL
100
A push or pull that changes the movement of an object
What is Force
100
Two basic types of simple machines
What are Lever & Inclined Plane
100
-Fulcrum is between the effort and load; -Push down to lift the load.
What is FIRST CLASS LEVER
100
A straight, slanted surface used to raised an object
What is an Inclined Plane
100
Why are simple machines an important part of our lives
What is they help make work easier
200
A measure of an object's speed and direction
What is Velocity
200
A beam or bar that pivots on a fixed point
What is a Lever
200
-Load is between the fulcrum and effort; -Pulling up on the effort side will lift the load;
What is SECOND CLASS LEVER
200
An example of an inclined plane
What is a ramp
200
One of the most influential Christians in the history of science
Who is Sir Isaac Newton
300
A metric unit used to measure work, equal to one newton meter
What is Joule
300
The weight you are trying to lift
What is the Load
300
-Effort is between the fulcrum and load; -Pulling/Pushing in the middle moves the load on the end.
What is THIRD CLASS LEVER
300
Why is effort decreased
What is steepness decreased of the slope
300
Force is equal to an object's mass multiplied by its rate of acceleration
What is Newton's Second Law of Motion
400
The change in an object's velocity over a period of time
What is Acceleration
400
The side that you use force on
What is the Effort
400
A wheel and pulley are the same
What is Lever
400
To figure the grade (steepness)
What is divide the RISE (the tallest point of the ramp) by the RUN (how long the run is)
400
W= force x distance
What is the math formula for work
500
The force that results when two materials rub against each other
What is Friction
500
The board that pivots on
What is a Fulcrum
500
Using a lever helps you to change the amount of force needed to lift this
What is a heavy rock
500
Another example of an inclined plane
What is Screw
500
Mass x acceleration
What is Force (measured in newtons)
