What is the force imparted by a 10 kg object accelerating at a rate of 5 m/s2? UNITS REQUIRED
10kg * 5 m/s2 = 50N (Newtons)
100
Define acceleration in terms of velocity and time.
Acceleration is a change in velocity over a change in time.

What is the speed of light (in a vacuum), in meters per second?
300,000,000 (3x108 or 300 million) m/s
100
What are the lowest-energy waves on the electromagnetic spectrum?
Radio waves

Who is the president of France? Last name is okay
Macron (Emmanuel Macron)
200
What is the acceleration due to gravity? WITH UNITS
9.8m/s2
200
What is the full name (first AND last) of the "godfather of modern physics"? (an apple hit him on the head and he was like "oh, gravity")
Isaac Newton
200
Which color light has the HIGHEST energy (lowest wavelength)?
Blue
200
What is the relationship between frequency and wavelength?
When one increases, the other decreases - they are inversely related.
200
What is it called when you make a cool hip-hop beat using only your mouth as an instrument?
Beatboxing
300
If a circuit has a voltage of 200 volts, and a current of 10 amps, what is the resistance of the circuit? WITH UNITS
V = I*R
V/I = R
200V/10amps = 20 ohms

A ball is picked up and held 10m off the ground. What kind of energy has it gained?
Potential energy
300
Why do transformers increase voltage?
To increase current - higher current (faster) means less electricity is lost (remember the bucket with a hole in it - run!)
300
What kind of a wave moves parallel to the direction of the energy it transmits?
Longitudinal
300
Which artist (or band) has sold the most records of all time?
The Beatles
400
A ball with a mass of 50kg is thrown with a velocity of 30m/s. Calculate the Kinetic Energy of the ball.
K.E. = 1/2mv2
K.E. = 1/2(50kg)(302m/s)
K.E. = 22,500 Joules
400
What is Newton's Law of Universal Gravitation?
F = G * m1m2/r2
400
What is Coulomb's Law?
F = K*q1q2/r2
400
What is the name of the effect that makes sirens sound higher-pitched when driving towards you, and lower-pitched when driving away from you?
The Doppler Effect

What is Bill Nye's real first name?
William
500
A cannonball with a mass of 482kg is fired from a cannon at 41 degrees above the horizontal at 18.382 m/s. At the moment the cannonball reaches the peak of its trajectory, what is its vertical velocity?
0m/s
500
State Newton's third law of motion.
Every action has an equal and opposite reaction.
