Unit 1: Motion
A measure of how much distance an object moves in a given time.
What is speed?
(Velocity also accepted)
This force keeps you from floating off the surface of the Earth.
What is gravity?
The second of Newton's Laws states that force is equal to this.
What is mass times acceleration
Feet, inches, meters and miles all measure this quantity.
What is distance?
(Position and location are also accepted)
The animal that is both alive and dead in Schrödinger's famous thought experiment.
What is a cat?
The European version of "miles per hour".
What is kilometers per hour?
This force only works on certain metals, like nickel and iron, but not on aluminum or copper.
What is magnetism?
What is opposite?
(Opposing also accepted)
Seconds, days, months and years measure this quantity.
What is time?
The energy of a photon is given by E = hf, where f is the frequency of the photon, and h is this.
What is Planck's constant?
This happens when an object changes its speed.
What is acceleration?
(Deceleration also accepted)
This force occurs when two objects slide past each other, creating heat.
What is friction?
The first of Newton's Laws says that an object moves at ______ velocity when net forces are zero.
What is constant?
A unit of distance, divided by a unit of time, measures this quantity.
What is speed?
(Velocity also accepted)
This experiment demonstrated that light and matter exhibit properties of both particles and waves.
What is the double-slit experiment?
A scalar has a magnitude but no direction. This has both magnitude and direction.
What is a vector?
The amount of acceleration felt by an object falling at terminal velocity.
What is zero?
(None also accepted)This quantity represents the amount of energy transferred between an object that exerts a force on another over some distance.
What is Work?
This unit measures weight, not in kilograms or pounds, but rather as a force.
What are Newtons?
The capital H in Schrödinger's Equation stands for this.
What is a Hamiltonian?
The fastest acceleration in the animal kingdom is found in this sea creature.
What is the mantis shrimp?
This theorem is used to add forces together when they are separated by a 90 degree angle.
What is the Pythagorean theorem?
1 g is the amount of gravitational acceleration on Earth. This number is the amount of meters per second squared in 1 g.
What is 9.8?
This unit measures energy, but isn't calories, kilowatt-hours, or horsepower.
What are Joules?
The trajectory of a quantum particle in an infinite square well can be fully described as a superposition of these trigonometric functions.
What are sines and cosines?
