Work & Energy
This type of energy is associated with the motion of an object.
What is kinetic energy?
This principle states that energy cannot be created nor destroyed.
What is the law of conservation of energy?
Momentum is calculated by multiplying an object's mass by this value.
What is velocity?
This is the name of Luke Skywalker's homeworld.
What is Tatooine?
The energy stored in an object due to its position in a gravitational field is called this.
What is gravitational potential energy?
As a ball is thrown up into the air, its kinetic energy is converted into this type of energy.
What is potential energy?
This unit is the standard unit for momentum in the metric system.
What is Newton-seconds (Ns)?
Usually accompanied by its iconic hand salute, this is a traditional Vulcan greeting.
If you lift an object into the air, you do work to increase its potential energy. If you lift it three times as high, you do this much more work.
What is three times?
For a swinging pendulum, its kinetic energy is at a maximum at this point in its swing.
What is the bottom/middle?
This is equal to an object's change in momentum.
What is impulse?
Commander Worf, cheif security officer aboard the USS Enterprise, was the first member of this species to join Starfleet.
What is a Klingon?
According to the work-energy theorem, the amount of work done on an object is equal to this quantity.
What is the change in energy?
A car, initially at rest, has 5000 J of potential energy at the top of a hill. As it coasts down the hill, if no energy is lost to friction/drag, the car will have this many joules of kinetic energy at the bottom of the hill.
What is 5000 J?
When two objects collide and bounce off each other, it is this type of collision.
What is an elastic collision?
To the elves of Middle Earth, Gandalf was known by this name.
Who is Mithrandir?
The velocity of an object triples. Its kinetic energy goes up by this factor.
What is nine times?
In real life, some amount of energy is usually lost to friction when doing work on an object. Energy lost to friction is usually converted into this type of energy.
What is thermal energy/heat?
In a perfectly inelastic collision, this quantity is NOT conserved.
What is kinetic energy?
This is the elven-smith who, during the Second Age of middle Earth, was manipulated into forging the Rings of Power by Sauron.
Who is Celebrimbor?
