Rube Goldberg Vocab
Simple Machines, Newton's Laws and chain reaction vocab
| Term | Definition |
|---|---|
| Rube Goldberg Machine | A machine designed to accomplish a simple task using several interconnected simple machines in a chain reaction process |
| 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 |
| Pulley | A simple machine that consists of a grooved wheel with a rope or cable wrapped around it that helps to lift object more easily Examples: Elevators or window blinds or a bucket in a well |
| Wheel and Axle | Two different sized circular objects that are attached together and turn as one Examples: Bike wheels or Car Tires or Gears in a watch |
| 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. |
| Who was Rube Goldberg? | Reuben Lucius Goldberg, ( July 4, 1883, —died Dec. 7, 1970,), American cartoonist who satirized (made jokes) about the American preoccupation with technology. His name became synonymous with any simple process made outlandishly complicated |
