TIME
Time multiplied by this gives distance
What is velocity (or speed)
A object in gravitational free-fall will continue to accelerate until it reaches this velocity.
What is Terminal Velocity
Your weight on Earth is equivalent to this
What is Mass
This is the "apparent force" that pushes you into the door of your car when making a sharp turn
What is Centrifugal Force
Measurements in a laboratory setting are always specified with % this, taking into account possible inaccuracies caused by people or equipment.
What is Percent Error
For an object experiencing parabolic motion, the time it will take to reach it's apogee can be found by taking the square root of two times the distance divided by this
What is acceleration
The gravitational force exerted on the Earth by the Moon, causes these forces that primarily effect the Earth's oceans.
What are Tidal Forces
This is found by multiplying an object's mass by it's velocity
What is Momentum
The velocity of an object in rotational motion can be found by the equation: x * radius / time, where x equals this.
What is two pi
King Henry I dictated that units in this measurement system be based on, among other things, the length of his own arm
What is the Imperial System
There are this many seconds in one hour
What is 3,600
This "point" is the name given to a location in space where the combined gravitational forces of two large bodies essentially cancel each other out.
What is the LeGrange Point
The Electric Force was unified with this one, as the apocryphal story goes, when James Maxwell literally came down from the mountain after trying to find his bearings during a lightning storm
What is the Magnetic Force
This force causes objects to follow a circular path, in the case of orbiting satellites, it is a force provided by gravity
What is Centripetal Force
Daily Double
Since 1879 the standard Kilogram or IPK, the standard from which all other units of the metric system are based, has been kept in a vacuum chamber in the basement vault of the Bureau International des Poids et Mesures in this country
Frequency is often represented with this alternate unit, not Hertz, derived from it's formula 1/T in seconds
What is seconds^-1
The center of a black-hole is referred to as a gravitational "this", containing a point of matter so dense that the laws of physics fall apart
What is a Gravitational Singularity
A vector represents a value that is composed of two distinct parts, direction, and this
What is Magnitude
Rotational inertia exerts force in this direction with respect to an object's circular path
What is tangent
Optical error caused by differences in the line of sight and apparent position of an object when taking measurements is known as this
What is Parallax Error
The effect of a clock moving slower at relativistic speeds, isn't the result of a trip to the optometrist, instead it's a consequence of Einstein's E-mc^2 and is known as time "this"
What is time dilation
Daily Double
The fact that the orbits of all planets in our solar-system are actually elliptical and not circular is due to this fundamental "law" governing gravity
This Greek letter is most commonly used to represent the engineering prefix for micro
What is Mu
This "force" is responsible for the differing rotation of tropical storms in the northern and southern hemispheres.
What is the Coriolis Force
One horsepower is equal to approximately 550 foot-pounds per second, equivilent to roughly 746 of these
What are Watts
