Simple Machine One of the six basic types of machines, which are the basis for all other forms of machines
Lever A simple machine that consists of a bar that pivots at a fixed point called a fulcrum Example: Seesaw or shovel or baseball bat or hockey stick
Inclined Plane A sloping flat surface set at an angle with no moving parts that is able to lift objects more easily by pushing or pulling the load Examples: Slide or ramp
Wedge A device that is this at one end and tapers to a thin edge at the other. Usually used to force a split or crack in another object Examples--> Axe or scissor or knife

Screw A simple machine that is an inclined plane wrapped around a central cylinder to form a spiral Examples: Drywall Screw or Looping Water Slide or tetherball screw
Mechanical Energy The amount of work an object can do because of the object's kinetic and potential
Potential Energy Stored energy that results from the position or shape of an object
Kinetic Energy The energy an object has due to its motion
Newton's First Law of Motion Law of INERTIA--> An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an outside force
Newton's Second Law of Motion The acceleration of an object depends on the mass of the object and the amount of force applied Example--> An empty shopping cart will accelerate faster than a full shopping cart when pushed with the same amount of force
Newton's Third Law of Motion For every action force there is an equal and opposite reaction force Example--> You push your arm back in the water and your body moves forward as you swim
Chain Reaction A series of events in which each event ending causes the next event to occur
Assembly Drawing a big picture view of the completed project and shows: 1.) a list of all the parts or components. 2.) the general arrangement of these components. 3.) how they fit together, and. the overall dimensions - but not the specifics.

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:

• SPACEBAR - flip the current card
• LEFT ARROW - move card to the Don't know pile
• RIGHT ARROW - move card to Know pile
• BACKSPACE - undo the previous action

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.
