Assumptions
Smooth surfaces have none of this!
What is friction?
r
What is distance to center of rotating object (or radius)?
If the net force on a 10m object is 20N forwards, this is its acceleration.
What is 2 N/kg forwards?
Your gravity on the moon is about this many times weaker.
What is 6 times weaker? (will accept anything from 5x to 7x)
An ideal string has none of this!
What is mass?
What is angle (of inclination)?
If you push a wall with a force of 5N west, this is the force the wall exerts on you.
What is 5N east.
These are Mr. Trauger's two most played operators.
Who are Jackal and Caveira?
A problem with a falling object that is not decelerating in the atmosphere assumes none of this.
What is air resistance?
μ
What is the coefficient of friction?
The gravitational constant near Neptune's surface is 25 m/s2. If you have a mass of 100kg, this is your weight on Neptune.
What is 2500N?
This American colony mysteriously vanished off the east coast, and nobody truly knows what happened to them to this day.
What is Roanoke?
An ideal pulley has none of this (name both).
What is mass and friction?
k
What is the spring constant?
If the weight of a block is 50N, but it is on a 30 degree incline, this is how much gravity pulls the block down the ramp.
What is 25N?
This scientist is famous for being among the first to test radioactive materials- and she is the first woman to win a Nobel Prize because she did so.
Who is Marie Curie?
An ideal spring obey's this law.
What is Hooke's Law?
A
What is some undisclosed number?
On a 53 degree incline with a coefficient of friction of 1/3, a 5kg block of mass on Earth experiences this much friction.
What is 10N?
This actress plays the green witch in the new Wicked movies.
Who is Cynthia Erivo?
