Newton's Laws
You are jumping off a diving board...as you jump down, the diving board pushes you back up...launching you into the air! SPLASH!! This is an example of which law of motion?
What is Newton's 3rd Law?
This term means "resistance to moving". An object's mass can affect this.
What is inertia?
This ancient scientist used only rational science--meaning he sat and thought to come up with ideas about science rather than empirical science which is making real observations and performing experiments.
Who is Aristotle?
This branch of science studies light and vision.
What is optics?
Newton demonstrated and proved this by shining white light through a prism, then shining one color of that spectrum light (lets say green) through a second prism.
Light is made up of a spectrum of colors and the prism is not creating or changing the light, only separating it.
Now, Uncle John is jumping off the diving board...he is able to launch himself higher than you did and lands with a MUCH BIGGER SPLASH!!! So much force that there isn't any water left in the pool..What law of motion does this represent?
What is Newton's 2nd Law?
In Scientific terms, the amount of matter an object is made of is called this.
What is mass?
This famous astronomer convinced Newton to publish his findings, and even helped finance the printing.
Who is Edmund Halley?
The name for the series of colored bands of light that are arranged in order based on their degree of refraction (bending) light through a prism.
What is a Spectrum? or What is the Rainbow/Light Spectrum?
It is said that Newton witnessed an apple fall from a tree and began to think about the force that keeps the moon tethered to the Earth...he does a thought experiment and discovers this theory about Universal Gravitation.
That the greater the mass of an object, the greater its attraction to another object AND that gravity weakens over distance AND that it applies everywhere!
I want to hit my little brother...I decide to just use my fist instead of a sock full of rocks because I don't want to hurt him too bad. Which law of motion does this represent?
What is Newton's 2nd Law?
When velocity changes (either increases or decreases), it is called this.
What is acceleration?
This person was a critic of Newton's and the two were rivals with each other; he also invented an improved compound microscope and published a book on what he saw: Micrographia; he also coined the term "cells" for the tiny holes seen in cork..which later became the term for biological cells.
Who is Robert Hooke?
When light waves bend or change direction as they pass through something (such as a prism), it is called this.
What is refraction?
The moon has a curved orbit around the Earth because of centripetal force--what does this mean?
The moon is moving "forward" at the same time that the Earth's gravity is pulling it "downward". The combination of forward movement and downward tugging keeps the moon in its circular path. Centripetal force is the name of the force that pulls at a right angle to its direction of motion...in this case, Earth's gravity would be the centripetal force.
I'm calmly floating in the vacuum of space and I let out a huge FART...now I'm flying towards the SUN!! And I can't stop!! What 2 examples of laws of motion am I representing?
What is Newton's 1st Law (inertia) and 3rd Law (release of gas propelled me forward)
This term is used to describe an object's speed in one direction.
What is velocity?
This French Scientist said there is more than just 'x' and 'y' on the dimensional plane...add a 'z' and now you have 3D!
Who is Rene Descartes?
Why is the grass green?
All objects contain substances/pigments that absorb color. The color you see is actually the one color that is NOT absorbed (it is reflected back at you) while all the others are absorbed. In the case of grass, or many plants, it is the chlorophyll that acts as the color-absorbing pigment, which reflects green.
Using Newton's 3 Laws of Motion, describe how a rocket is launched from the Earth.
1st: The rocket sits on the launchpad..and will continue to sit there at rest unless acted upon by an outside force.
2nd: In order to launch the rocket, the force (the effort needed to make the rocket rise upwards) must be greater than the mass of the rocket times the acceleration (the burning of the propellant pushing it forward)
3rd: As the propellant burns, it's force thrust is downwards, which the rocket reacts with equal/opposite reaction force upwards.
Santa is out delivering the last 2 presents on Christmas night...the reindeer come to a quick stop and those 2 presents fly out of the sleigh and smash into the side of the house. The PS5 is totally destroyed but the Rubik's cube is fine! What 2 Laws of motion does this represent?
When we are measuring the force exerted on an object by gravity, we are essentially measuring this.
What is weight?
This English poet wrote about the year 1666: Annus Mirabilis, or the Year of Wonders. During this year, the English were victorious over the Dutch, London had a Great Fire, a plague spread across Europe, and Newton made major scientific breakthroughs: theory of universal gravity, calculus foundation, color theory, and the beginnings of the laws of motion.
Who was John Dryden?
White light is a simple, homogeneous blend of ALL color wavelengths (an infinite amount!! We can only see the ROYGBIV). But a complete absence of the color wavelengths gives us this.
What is Black?
Newton found that the algebra and math of his day was not enough for the complex calculations that he needed, so he developed Calculus! What exactly does that mean?!
When you need to measure a "moving" target, such as the constantly changing speed, direction, acceleration of a planetary orbit or the trajectory of a cannonball that is pulled down by gravity. It measures closer and closer intervals, but never reaching zero.
