How many meters are in a kilometer?
100
Cubit - A biblical unit of distance. It is the distance between a man's middle finger and his elbow. It is about 18 inches or 45 centimeters.
State Newton's first law.
an object at rest remains at rest and an object in motion remains in motion unless acted on by an unbalanced force.
The energy of motion.
What is kinetic energy?
Another term for “distance” in a certain direction.
What is "displacement"
A form of energy resulting from the existence of charged particles (such as electrons or protons), either statically as an accumulation of charge or dynamically as a current.
What is Electricity?
What is the SI Unit for Distance?
meter
Smoot - one smoot is defined as 5 feet and 7 inches (1.7 m), the height of Oliver R. Smoot, then an MIT undergrad who during his fraternity pledge was used by his fraternity brothers to measure the length of the Harvard Bridge between Boston and Cambridge, Massachusetts. They simply laid him down on the bridge and drew a mark where his head was, repeated the entire exercise along the bridge, and got a value of 364.4 smoots plus or minus one ear.
State Newton's second law (usually expressed as a formula).
What is f=ma
Stored Energy
What is Potential Energy?
Speeding up OR changing direction are both examples of this.
What is acceleration?
A physical phenomenon produced by the motion of electric charge, resulting in attractive and repulsive forces between objects.
What is magnetism?
What is the SI unit for mass?
the kilogram
Fun Fact:
Scoville - Named after its creator, chemist Wilbur Scoville, this unit measures the hotness of a chili pepper. A scoville is the dilution factor of a solution of chili pepper extract until the "heat" (the amount of the chemical capsaicin) is no longer detectable to tasters.
State Newton's Third Law
For every action there is an equal and opposite reaction force.
What is Potential energy?
Energy stored in an object due to its position, state or shape
The speed of an object in a particular direction
What is velocity?
The interaction of electric currents or fields and magnetic fields.
What is electromagnetism?
This converts to 1000 cm?
What is 10 m?
BEARD-SECOND (DISTANCE)
A unit inspired by the light-year, but for extremely short distances. A beard-second is defined as the length an average physicist’s beard grows in a second (about 5 nanometers).
The tendency of an object at rest to remain at rest or, if moving to continue moving at a constant velocity.
What is Inertia?
1/2 mass times velocity squared
What is the formula for kinetic energy?
Force has both magnitude and ___
direction
These types of waves have the shortest wavelength in the electromagnetic spectrum.
What are gamma rays.
The length of 10 millimeters.
What is 1 cm or .01 meters?
SHEPPEY (DISTANCE)
A sheppey is defined as the closest distance at which sheep remain picturesque, which is about 7/8 of a mile.
The unit is the creation of Douglas Adams and John Lloyd, included in The Meaning of Liff dictionary of objects for which no name exists.
According to the Second Law of Motion, if the force on a body doubles, the acceleration _____.
What is doubles?
The acceleration due to gravity is ___ m/s2
9.8
This occurs when two forces acting on an object are balanced
What is nothing?
These types of waves have the longest wavelength in the electromagnetic spectrum.
What are radio waves.
