Principles of Physics
The force that attracts an object toward the center of the Earth.
Gravity
This scientist "discovered" gravity.
Isaac Newton
This toy consists of colored blocks you use to build structures.
Lego
This machine is a simple wheel and rope that can be used to lift heavy objects.
Pulley
A structure that is used to cross over a divide such as a river or a gorge.
Bridge
The amount of movement an object has until it comes to rest.
Momentum
This scientist is famous for his equation e=mc2.
Albert Einstein
This toy uses gravity and momentum to make a small disk go up and down from your hand.
Yo-yo
A moveable bar that pivots on a fulcrum.
Lever
A structure that allows a small glass ball to roll down a course.
Marble Run
The principle that explains why a boat floats on water
Buoyancy
This scientist is also known for such artworks as the Mona Lisa and The Last Supper.
Leonardo Da Vinci
This playground toy is a lever that two people sit on to go up and down.
Seesaw
A simple machine that allows an object to move, using gravity, down an inclined surface.
A structure designed to be taller than it is wide.
Tower
The principle that explains how an object can move against gravity using some sort of push.
Thrust
Hooke's Law of elasticity was named after this English scientist.
Robert Hooke
One of three scientific principles that make a Slinky toy go down the stairs.
Gravity, momentum, elasticity
These round objects, used with an axle, allow for objects to roll.
Wheel
A structure that uses physics to shoot an object.
Catapult (or trebuchet)
The ability for an object to maintain its normal shape after being stretched.
Elasticity
This CEO of SpaceX and Tesla Motors plans to send people to Mars in the near future.
Elon Musk
This game, known for taking blocks from the bottom of a tower and placing them on top, uses many of the physics principles we learned in class.
Jenga
A complicated machine designed to perform a simple task like turning a page in a book. Named after an American cartoonist.
Rube Goldberg Machine
This is a simple bridge that needs nothing to hold the pieces together.
