Kinematics and Force
This quantity is found by taking the integral of Force dot d t and is equal to the change in momentum.
What is impulse?
How many attempts should you get on WebAssign?
What is Unlimited or You complain to Hardcastle about the amount and ask for more.
A particle moves such that its speed is constant but its velocity is not. This must be true about its path
What is it is curved?
For a particle under a central force, this quantity remains constant and leads directly to planar motion.
What is Angular Momentum?
You see Hardcastle years from now, what hand signal is he likely to make as he greats you?
What is the right-hand rule (aka the Physics gang sign)?
What theorem is useful for figuring out the moment of inertia when an object isn't rotating about its center of mass?
What is the Parallel Axis Theorem?
For an object to just barely escape a planet's gravitational field, the object's initial Universal gravitational potential energy will be equal to this quantity.
What is the object's initial kinetic energy? (Or KE at lift-off)
What is a reason bean?
What is slang for "reason being" that only the cool AP kids know?
Also accepted is MCQ tricks for getting the answer without getting the answer
The direction on the net force on an object moving in a circle.
What is towards the center?
A force can be thought of as the derivative of a potential energy if it has what property?
What is it is conservative or the work it does is path indepenedent?
You roll a solid disk and a ring with the same mass down a ramp. Which will get to the bottom first?
What is the solid disk, since it has a lower moment of inertia?
An object going in a circular orbit increases it speed slightly. How does its orbit change?
What is becomes an elliptical orbit that takes the object further away and where the original radius of the circular orbit becomes the point when the object is moving the fastests?
Hardcastle has made a mistake on the board. How does he correct it?
What is
- Erase the board with his bare hand, even though an eraser is next to him?
- Silently stare at the board for an awkward amount of time?
- Mumble that it is "relatively straightforward" and move on to the next topic?
In non-uniform circular motion, this component of acceleration is responsible for changes in speed along the path.
What is tangential acceleration?
Two collisions have the same initial momentum. One is elastic, one is perfectly inelastic. This is how their final kinetic energies compare.
What is the elastic collision has higher final KE?
A ball is rolling up a ramp and slowing down. In which direction does friction act?
What is up the ramp, since the rotation of the ball is slowing down?
In simple harmonic motion, what is the phase angle?
What is a shift of the sin or cosine you need to do to make sure the system has the correct initial position and velocity?
What is something you can count on Hardcastle to do in class?
What is
- Make a corny Physics joke?
- Laugh at his own jokes but not others' jokes?
- A seemingly endless monologue?
- retell you a story he actually already told you before?
