SI Units
Unit for length
What are metres?
Clair drops her calculus test and a brick at the same time. However, the brick falls faster. This force is responsible.
What is air resistance?
When someone spins a ball on a string and then lets go of the string, the ball flies off in a straight line. This happens because it no longer experiences this force.
What is centripetal force?
The particle which, out of protons, neutrons, and electrons, has the least mass.
What are electrons?
Unit for force (hint: F = ma)
What are Newtons, which equal kg * m/(s^2)
The answer to Clair's homework question, which asks what 50 Celsius is in Kelvin
What is 323 K?
Rat #1 is twice as heavy as Rat #2. On a see-saw, how much farther away from the middle does Rat #2 have to sit for equilibrium to be reached?
Twice as far
This phenomenon causes a pencil in a glass of water to appear "broken" (or bent)
What is refraction?
Unit for electric charge
What are Coulombs, which are Amperes/second?
The kinetic energy of a 1 gram goldfish thrown by Clair at 2 m/s
What is 1/8000 Joules?
A spring is compressed by twice as much as another spring. How much more energy is stored?
4 times as much
A material which allows electric current (moving electrons) to pass through
What is a conductor?
Unit for energy
What are Joules, which equal kg * (m^2)/(s^2)?
Clair puts her hot coffee outside and it cools down. What happens to the entropy of the COFFEE?
Decreases (i gave up on the Jeopardy question format)
The upward force exerted by a fluid that opposes the weight of an object immersed in it.
What is buoyancy?
This happens to the pressure of a gas as temperature increases.
Increases
Unit for resistance
What are Ohms? (SI Units: kg * m^2 * A^-2 * s^-3)
The day of the week on which Clair was born
What is Tuesday?
A block slides down a frictionless ramp (30 deg incline). This is the acceleration.
What is 1/2 * g?
The reason why mirages form.
What is refraction caused by differences in air density and temperature?
