Rotational Motion and Gravity
The product of force and lever arm that causes rotation.
What is Torque?
The curved path followed by a projectile.
What is a parabola?
Mass per unit volume measure this.
What is density?
The Hertz (Hz) is used to measure this.
What is frequency?
This is the shortest book in the Old Testament.
What is Obadiah?
In orbit, astronauts feel weightless because they are in this state of motion.
What is free-fall?
In elliptical orbits, a satellite moves fastest at this point.
What is perigee?
Pressure in a liquid increases with this.
What is depth?
In this type of wave, energy moves along the direction of the wave.
What is a longitudinal wave?
The only miracle of Jesus recorded in all four Gospels.
Big 'G' was calculated by Henry Cavendish and was used to determine the mass of which object?
What is the Earth?
The launch angle for maximum range on level ground (no air resistance).
What is 45 degrees?
A hydraulic lift is an application of this principle.
What is Pascal's Principle?
When two waves add constructively or destructively.
What is interference?
“Love your neighbor as yourself” (quoted by Jesus) comes from this Old Testament book.
What is Leviticus?
This type of force is considered a fictitious force.
What is Centrifugal force?
How fast does the International Space Station orbit the Earth?
What is 90 minutes?
The principle stating buoyant force equals the weight of displaced fluid.
What is Archimedes’ principle?
The apparent change in frequency due to relative motion.
What is the Doppler Effect?
In Revelation, this church is rebuked as being “lukewarm.”
What is Laodicea?
According to Newton, gravity follows this mathematical relationship with distance.
What is the inverse-square law?
This is the speed a satellite must travel to fall around the Earth.
What is 8,000 m/s (or 28,000 km/h or 17,500 mph)?
Bernoulli’s principle: Faster fluid flow leads to this in pressure.
What is lower pressure?
This is the relationship between the period and length of a pendulum.
What is the period is directly proportional to the square root of the length (or vice versa - square of period ~ to length).
This Roman centurion became the first Gentile convert to Christianity after Peter visited him following a vision.
