Scientists
This man discovered gravity and calculus, but not fig pastries
Fnet=ma
The Earth is just as attracted to you as you are to it
(Every action has an equal and opposite reaction)
Change in velocity is...
acceleration!
True! This is called resonance.
This German-born scientist formulated the famous equation E=mc^2, but originally failed the entrance exam into his desired college
Albert Einstein
When two things collide, bad things can happen, but it can be a little easier if you use this long equation
p1 + p2=p'1 + p'2
Matter (what everything is made out of) is a type of energy
True
(E=mc^2)
Maybe the Star Wars franchise had it right, with this push or pull that causes an object to speed up or slow down...
Force
When you put ice cubes into a drink causing it to become cold, does the
a) heat from the drink go into the ice, melting it
b) the coldness from the ice leak into the drink
c) the heat and cold travel back and forth until reaching a steady temperature
Answer: A
This physicists wrote the best-selling novel "A Brief History of Time" and theorized that black holes emit radiation, all while slowly becoming paralyzed from Lou Gehrig's disease
Stephen Hawking
This equation is used to calculate how much something is speed up, or slowing down
a=delta v/time
The speed of sound is thirteen times slower than the speed of light
False.
Sound is 900,000 times slower than light
Sometimes, we like to save things for later, just like the energy that is stored in a system
Potential Energy
Increasing the voltage of a battery will do what to the electricity moving through a circuit?
a) maintain (keep the same)
b) decrease
c) increase
Increase!
This scientist did remarkable research on radiation, but that radiation eventually gave her cancer, leading to her young death
Marie Curie
Not everyone likes Work, but you can always set it equal to the change in...
Energy!
W=deltaE
The Universe is 50% dark energy and dark matter, and 50% regular energy and regular matter. Ying and yang.
False! The universe is 95% dark energy and dark matter.
Car crashes aren't great, especially if the cars bounce off of each other in this type of collision
Totally inelastic collision
Sounds travels fastest in:
1) Air
2) Steel
3) Water
Answer: 2) steel
The first African-American to work for NASA, this American mathematician calculations of orbital mechanics as a NASA employee were critical to the success of the first and subsequent U.S. crewed spaceflights
Katherine Johnson
Fg=Gm1*m2/r^2
True! We only know about them because of the forces they emit on other particles. Trippy.
Just like earthquakes, sometimes we measure things in terms of their strength and ignore directions like a lost man when a question uses this word
Magnitude
Which of the following has the highest amounts of energy?
a) Ultraviolet rays
b) X-rays
c) Visibile rays
Answer:
b) X-rays
