The Physics of Motion
This quantity tells you how fast something is moving and the direction it is moving in.
What is velocity?
This law explains why passengers lurch forward in their seats when the car comes to a sudden stop.
What is Newton's First Law (the law of inertia)
What is gravitational potential energy?
Work is only done when a force causes an object to do this.
What is move (or have displacement)?
Jedi Knight Anakin Skywalker became known by this name after falling to the Dark Side and swearing his loyalty to the Sith.
Who is Darth Vader?
A car travelling in a straight line at a constant velocity of 20 m/s for 5 seconds covers this distance.
What is 100 meters?
A 2 kg object experiences a force of 6 N. Its acceleration is equal to this.
What is 3 m/s2?
This type of energy depends on an object's motion.
What is kinetic energy?
You apply a force of 200 N to a wall, but it does not move. This much work was done on the wall.
What is 0 J?
These inhabitants of Middle-Earth are known for their short stature, love of food and drink, and big, hairy feet.
What are Hobbits (Halflings)?
A ball that is thrown straight up into the air has this velocity at the peak of its trajectory.
What is zero m/s?
What is Newton's Second Law?
What is kinetic energy?
A 10 N force moves a chair 3 m from its starting position. This much work was done on the chair.
What is 30 J?
Emperor Paul Muad'dib Atreides built his palace on this planet, the homeworld of the Fremen and the only known source of the valuable Spice Melange.
What is Arrakis (or Dune)?
This quantity is equal to the rate of change of an object's velocity.
What is acceleration?
According to Newton's Third Law, when you push on a wall, the wall does this to you.
What is push back with an equal and opposite force?
A 1 kg ball moving at 4 m/s has this much kinetic energy.
What is 8 J?
The Work–Energy Theorem states that the amount of work done on an object is equal to this.
The Lady Galadriel and her husband, Celeborn, ruled this woodland realm located east of the Misty Mountains, whose name in Elvish translates to "Dream Flower."
What is Lothlórien (Or Lórien)?
The acceleration due to gravity on Earth is approximately this value.
What is 9.8 m/s2?
An object can be said to be in this state if the net force acting on it is zero.
What is equilibrium?
In a closed system with no friction, the total mechanical energy in the system does this over time.
What is stay the same (is conserved)?
This happens to an object's kinetic energy when negative work is done on it.
What is decreases?
Before Sauron terrorized middle Earth during the Second and Third Ages, this being was the original Dark Lord. He used to be one of the Valar before becoming evil and swearing to destroy all the works of Eru Illuvatar.
Who is Morgoth (or Melkor)?
