Motion
This is the shape that a projectile makes as it travels.
What is a parabola?
This force arises when a rope or chain is used to move something or hold something still.
What is the Tension Force?
What conserved quantity requires that an angle (relative to you the observer) be swept out as it moves?
What is Angular Momentum?
This term refers to how much heat a substance in one phase can hold before beginning to turn into another phase.
What is the heat capacity?
These are the units of Force.
What are Newtons?
True or False: Upon release, an object that is originally moving in a circle will continue to move in a circle.
What is False. It moves in a straight line. An object in motion tends to stay in motion unless acted on by a force. This is just Newton's 1st Law.
What is an inverse square law?
This type of energy is associated with motion.
What is kinetic energy?
This type of transfer requires that two objects be touching.
These are the units of momentum.
What are kg*m/s? (P = MV)
True or False: It is possible for an object to have a constant speed, but be accelerating.
This is the name for the proportionality constant found in the equations for friction.
What is the coefficient of friction. (This actually comes in two types: kinetic and static.)
This type of energy is associated with position or arrangement.
What is potential energy?
This type of heat transfer requires a fluid such as a liquid or gas.
What is convection?
These are the units of angular momentum.
What are kg*m^2/s? (L = rmv)
True or False: When traveling in a circle, the acceleration points inwards toward the circle.
What is True? Remember that acceleration is the change in velocity. That is, its direction is changing. The change in this direction points inward.
True or False: An object traveling upward takes a longer amount of time to get to its peak than the same object falling back down.
What is False? The time to go upward takes LESS time because there are TWO forces acting against it while it is headed up. On its way down there is only one force acting against its motion and it takes more time.
This quantity is a rough measure for the average amount of kinetic energy that a system has.
What is temperature?
This type of heat transfer requires particles such as light.
What is radiation?
True or False: Heat and Work both have units of energy (Joules).
True or False: The centripetal (or centrifugal) acceleration goes off like the square of the velocity.
What is true? a_c = v^2 /r.
This is the proportionality constant associated with universal gravitation.
What is G? Remember that proportionality constants do two things. They make units work and give the correct scaling.
True or False: Entropy is a conserved quantity in a closed system.
What is False? The second law of thermodynamics says that the entropy is always increasing (or zero but this is very unlikely if a process is rearranging something).
This object is a good example of a closed system.
What is a thermos?
True or False: The units of entropy are J/K.
