Work & Simple Machin

BMS Science

simple machine basic machines used to make work easier.
input force force that is needed to do work.
output force force the machine exerts after the input force.
force can act between objects that are in direct contact or over a distance.
friction a force that holds back the movement of a sliding object.
gravity a force that causes objects to fall to the ground.
weight the force of gravity on an object.
Newton the unit of measurement of force.
work a mathematical relationship between the amount of force needed for the object to move and how far it moves.
Joule the unit of measurement of work.
mechanical advantage indicates how useful a simple machine is for performing a given task by comparing the output force to the input force period.
lever a simple machine that reduces the effort force needed to lift a heavy object by applying the force at a greater distance from the fulcrum of the lever.
pulley a simple machine that reduces the effort to lift a heavy object by applying the force through a greater distance such as pulling more rope through the pulley.
inclined plane a simple machine that reduces the effort to raise an object to a given height.

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:
