#### Transcript of Physics of a Rube Goldberg Machine

Rube Goldberg Machine
A: A machine that completes a simple task in a complicated way
What is a Rube Goldberg Machine??
Who was Rube Goldberg??
How will Rube Goldberg Machines help our everyday life??
What is the point of a Rube Goldberg Machine?
This is our Rube Goldberg Machine!!!

Rube Goldberg was a famous cartoonist who drew complex ways of transporting one thing to another.
Rube Goldberg was born on July 4, 1883.
He was a sculptor, inventor, and cartoonist for newspapers.
Rube Goldberg graduated from Cal Berkeley with a degree in engineering.
He became a Pulitzer prize winner, and an engineer for the City of San Francisco and Sewer Department.

By teaching us new ways to transport objects quickly and efficiently.
We can learn new engineering techniques.
Rube Goldberg Machines can help us get things a lot faster.
Example: If you are working on a project and you get thirsty, you can push a domino, or pull a lever and you can get water to you in a fun, easy way.
Rube Goldberg machines are made to transport or do something in a fun, amusing way.
Rube Goldberg Machines can be made from practically anything, from pencils to dominos.
Rube Goldberg machines are a good way to have fun with your stuff, at whatever age you are.
Anybody can build a Rube Goldberg Machine, and everybody can have fun doing it.
Q: What is a Rube Goldberg Machine?
The physics behind it.
Newton's First Law of Motion
Newton's First Law of Motion
states that an object will remain
at rest or moving at a constant
velocity unless acted upon by an
unbalanced force. For example,
the force from a roll of duct tape
is an unbalanced force to a set of
dominos, causing the dominos to
tip over.
Newton's Second Law of Motion

Newton's Second Law states that
the acceleration of an object depends
on the net force acting on the object,
and the object's mass. For example,
if someone is pushing their car, and
their car is very heavy, it will require
more force to get the car to start
rolling.
Newton's Third Law of Motion
Newton's Third Law states that if one object exerts a force on another object, the second object will experience a force of equal strength in the opposite direction of the first object. For instance, if I get in a car accident with a wall, my car will experience the same force as the wall, but in an opposite direction.
Energy
Kinetic Energy
Kinetic Energy is Motion Energy
It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity.
Kinetic Energy is found when an object is in motion, or is moving.
Kinetic Energy can be found in anything. From ordinary People to Roller Coasters.
Potential Energy
Potential Energy is the energy of an object or a system due to the position of the body or the arrangement of the particles of the system.
Potential energy is often associated with restoring forces such as a spring or the force of gravity.
Friction
There are many different types of friction, but we will only talk about: Sliding Friction, Fluid Friction and Rolling Friction

Sliding Friction
Sliding Friction is when 2 objects slide across another, like paper on a table

Fluid Friction
Fluid Friction is when an object goes through or is engulfed by a fluid. Air resistance is fluid friction. An example is like when a bird is flying through the sky.

Rolling Friction
Rolling Friction is just like Sliding Friction, except the object is rolling. Rolling Friction is when an object is rolling across another object, like when a ball is rolling across the ground.
