Dynamics
A branch of physics that focuses on force and how they relate to motion.
The Problem of Classical Mechanics
When this branch of physics was first developed, scientists were trying to solve a particular problem, known as_______
solve, goal
The Problem of Classical Mechanics is not a problems, however it tries to _______/get to a _______.
Isaac Newton:
solved the problem of classical mechanics for most real-world situations.
gross, slow moving objects
Isaac Newton's solution applies specifically to_______
Slow-moving
anything going less than 99% the speed of light. objects that may range in size from an atom to a galaxy.
tiny(subatomic), fast moving objects
Isaac Newton's solution doesn't apply to_______
atom, galaxy
Newton's method works with objects that may range in size from an _______ to a _______
small, fast
predict the motion of the really _______ stuff and special relativity (Einstein) dealt with the really _______ stuff.
quantum mechanics
Branch of physics concerned with the microworld based on wave functions and probabilities, introduced by Max Planck (1900) and developed by Werner Heisenberg (1925), Erwin Schrodinger (1926), and others.
special relativity
invented by einstein in 1905. Branch of modern physics that deals with really fast stuff (greater than 99% the speed of light)
tiny, fast
Modern physics deals with the Problem of Classical Mechanics for _______ and _______ objects
4)
1642-1727, the laws of motion, the universal law of gravitation, calculus, work in optics, inventing the reflecting telescope
the laws of motion and the universal law of gravitation
Two of the four principal accomplishment that were a big part of Newton's solution of the Problem of Classical Mechanics.
refracting, mirror, lens, reflecting
Newton re-invented 1st telescope Galileo used for astronomy, called the _______ telescope. He used a _______ instead of a _______, and was called the _______ telescope
optics
branch of physics that studies the properties of light
image
..., a copy of an object formed by reflected or refracted rays of light
cameras, telescopes
images are needed for many optical instruments like _______, microscopes, _______, projectors...
To create a clear picture:
each point on the screen should receive light from only one point on the object. This way colors would be seen, but the image would be upside down.
images are formed by:
taking all of the light that diverges from each point on an object and forcing it to converge to unique points on a screen, so that each point on the screen receives light from …
pinhole, convex lens, concave mirror
only three things exist that are capable of producing an image:
A pinhole: barrier placed between object and screen with a pinhole, achieves to form an image by:
only allowing one ray from each point on the object to reach the screen, because the pinhole is small.
Pros and Cons of pinhole:
the smaller the pinhole, the sharper the image. If more rays were to pass, the image would blur. but since the hole is small, the image is dim. The image turns out upside down.The fur…
rays still get through and can damage your cells.
Solar eclipses: If you look at a parcial solar eclipse with your eyes you could damage your sight because:
convex lens
..., a lens that is thicker in the middle than at the edges
convex lens pros
you can se the image better because there is more light being used. The image looks sharper. Image brighter than with pinhole
convex lens cons
there is only one distance form lens to screen that will work. If not the image blurs
objective, more, brighter, magnifies
studied and it forms an image with it. The larger this lens, the _______ light it collects, the _______ the image. A second lens (the eyepiece) then _______ this image
Galileo, 1609-1610,
Milky Way was composed of myriad, tiny, distant stars.
distant, dim, objective, light
distantly and make more discoveries
2, heavy, thick, absorbing, distorting
_______ much of the light that attempted to go through it.
objective, concave mirror, reflecting, magnify, 8.2
again grow bigger. The largest single reflecting telescope today has a diameter of some _______ meters.
purpose of a telescope
magnify things that are big but look small and make them bigger
purpose of a microscope
magnify things that are close but small and make them bigger
focal point
..., the point at which light rays parallel to the optical axis meet when reflected or refracted
Principle Axis
a straight line that passes horizontally through the center of the lens (or mirror)
Focal Length (f)
the distance from the center of the lens to the focal
Object Distance (o)
the distance from the object to the center of the
Image Distance (i)
the distance from the image to the center of the lens.
magnification (M)
measure of how much larger or smaller an image is compared with the object itself
The Thin Lens Equation: 1/o + 1/i = 1/f
sin…
mirrors, same
point, the object, and the image are all on the _______ side of the mirror.
