what is an inclined plane
Inclined plane, simple machine consisting of a sloping surface, used for raising heavy bodies.
what is an wedge
A wedge is simply a triangular tool, often made of metal, wood, stone, or plastic.
what is an screw
A screw is a mechanism that converts rotational motion to linear motion, and a torque (rotational force) to a linear force.
what is an lever
A lever is a simple machine made of a rigid beam and a fulcrum.
what is a pulley
A pulley is a wheel that carries a flexible rope, cord, cable, chain, or belt on its rim.
what is a wheel and axle
what is a force
Force is a Vector Quantity. A force is a vector quantity. As learned in an earlier unit, a vector quantity is a quantity that has both magnitude and direction.
what does vertical mean
at right angles to a horizontal plane; in a direction, or having an alignment, such that the top is directly above the bottom
what does horizontal
parallel to the plane of the horizon; at right angles to the vertical.
what does Fulcrum mean
the point on which a lever rests or is supported and on which it pivots.
what does simple machines mean
A simple machine is a mechanical device that changes the direction or magnitude of a force.
what is bad friction
Bad friction takes away a user's autonomy and traps them in an impenetrable “black box” system, where users cannot decipher how their data is being used.
what is good friction
Good friction is human-first. It engages users in decision-making during the conversion process and ultimately can lead to brand endorsement.
what is First class lever
First class levers have the fulcrum between the force and the load.
what is second class lever
Second class lever. In second class levers the load is between the effort (force) and the fulcrum.
what is third class lever
Third Class Lever, these are the levers in which the fulcrum is at one end and the force is applied in the middle and the weight is on the other end.
what is EFL
first class lever
what is ELF
second class lever
what is LEF
third class lever
what can a pulley do
Pulleys are powerful simple machines. They can change the direction of a force, which can make it much easier for us to move something. If we want to lift an object that weighs 10 kilograms one meter high, we can lift it straight up or we can use a pulley, so we can pull down on one end to lift the object up.
what can a inclined plane do
The purpose of an inclined plane as a simple machine is to move something from a lower height to a higher height with less effort.
what can a wedge do
It can be used to separate two objects or portions of an object, lift up an object, or hold an object in place.
what can a screw do
The most common uses of screws are to hold objects together — such as wood — and to position objects.
what can a lever do
A lever amplifies an input force to provide a greater output force, which is said to provide leverage, which is mechanical advantage gained in the system, equal to the ratio of the output force to the input force.
what can a wheel and axle can do
The wheel and axle is a simple machine consisting of a wheel attached to a smaller axle so that these two parts rotate together in which a force is transferred from one to the other.
