These are the appropriate base units of physics
What are kilograms, meters and seconds?
This is the net force is 400 N pull east and 700 N pull west
What is 300 N [west]
This is the guy with a moose and the scientist that may have "helped" him die
Who are Brahe and Kepler (in order!)?
This is the height from which a ball was dropped if it is travelling 35.4 m/s just before striking the ground
What is 64 m?
This is the classification for 200 nm light
What is ultraviolet?
This is the equation you CANNOT use if there is acceleration.
What is v = d/t?
This is the net force VECTOR if 54 N pulls north and 87 N pulls east
What is 102 N at 31.8 degrees Nof E
This is what you should equate for a truck driving on level ground around a curve in the road
What is Force centripetal = Force friction?
This is the meaning, in joules and seconds, of "60W" printed on a lightbulb
What is 60 J of energy in 1 second?
These are 2 HUGE difference between light and sound waves
What are their speed and mode of travel (light needs no medium, sound does!)?
On a map, these directions are typically described as negative
What are south and west?
These are 2 useful rules for a pulley system
What is the rope transmits the same tension at all points, and the objects accelerate with same magnitude? (also pulley is frictionless, rope is massless, rope does not stretch)
This is the equation for any object at the bottom of a vertical circle
What is Fc = Ft - Fg?
An object is dropped from 30 m above ground - this is what did the work.
What is Earth's gravitational force? (only forces do work, and fields are regions where a force may act)
This is the period of a 45 cm pendulum with 75 g bob on Mercury.
What is T = 2.2 seconds?
This is the rearrangement of the timeless equation for displacement
What is d = (vf2 - vi2)/2a?
On a 13 degree incline, this is the Fg-parallel that would slide object "m" down the ramp.
What is mgsin13?
This is the period of a wheel spinning at 345 rpm
What is T=0.17s?
This is the centripetal force VECTOR on a 400 g object spun horizontally on a 20 cm string at a rate of 12 Hz
What is 455 N [toward center]?
This is the length of a closed pipe needed to resonate a 45 cm sound wave at its 3rd harmonic
What is a 34 cm pipe?
This is the time when an object decelerating at -5 m/s2 comes to a complete stop over a distance of 25 m
What is 3.16 seconds?
This is the friction coefficient if two equal masses are slung over a Fletcher's trolley and the system accelerates at 1.78 m/s2
What is the mu = 0.637?
This is what you can calculate if you take 365 squared / 1.50E11 cubed.
What is Kepler's constant for our solar system?
This is the factor by which escape velocity EXCEEDS orbital velocity for any object.
What is Square Root of 2?
This is the source frequency if it's heard at 500 Hz when the observer is standing still but the source is leaving at 120 km/h on a 0C day.
What is 550 Hz?
