General
When a force moves an object over a distance.
What is work?
The object being lifted is the __________.
What is the load?
Another name for an inclined plane is a ____________.
What is ramp?
A wheel with a rope around it is ______________.
What is pulley?
The wheel and axle is made up of two parts: the wheel that turns on a post, which is called the __________.
What is axle?
A compound machine uses (one/multiple) part (s) doing work
What is multiple
Another word for the effort put into moving the load on a lever (or any simple machine) is called:
What is force?
If you use an inclined plane, the distance is longer, but it takes less _______________.
What is force?
The pulley uses a ____________ and rope to lift a load.
What is wheel?
You create a screw when you wrap on inclined plane around a __________.
What is a post?
This is a device that makes work feel easier. (It decreases the force you need to do the same amount of work).
What is a machine?
The pivot point on a lever is a _______________.
What is fulcrum?
An inclined plane is a simple machine that is a flat surface that is ___________ at one end.
What is higher?
Two inclined planes placed back to back make this simple machine.
What is a wedge?
A screw uses ______________ force than pounding a nail.
What is less?
This is the advantage that a simple machine provides by reducing the amount of force we need in order to do work.
What is mechanical advantage?
There are ___________ classes of levers.
What is three?
The inclined plane is used to ___________ an object.
What is raise?
A wedge changes the __________ of the force
What is direction?
In a wheel and axle, both part _______ at the same time.
What is rotate?
For the same amount of work, if I increase the distance over which a force is being applied, I can (decrease/increase/keep the same) the force I need to apply.
What is decrease
A lever can let you reduce the amount of a force you need to exert or it can change the _________ of the force you exert.
What is direction?
Inclined planes may have been used to build the _______________ of Ancient KMT because the blocks were too heavy to move without heavy equipment.
What are pyramids?
To decrease the force applied lift an object with a pulley, increase the length of the _____________.
Rope
Just like an inclined plane, a screw moves a longer distance, but less ____________ is needed.
What is effort?
