Centripetal Motion
The resultant direction of the velocity if an object is attached to a string and spun in a circle and then the string is cut.
Tangent to the circle.
The period of an orbit for a planet that has an orbital radius of 1AU from its parent star.
1 year. <- This is Earth.
When calculating the torque as a function or the force and radius, the direction of the torque is given by this rule.
The right hand rule.
The equation for rotational kinetic energy.
E = 1/2 I (omega)2
Dr. Culbreth's favorite character from ATLA.
Uncle Iroh
The location of highest normal force on an object moving in a vertical loop.
The bottom of the loop
The two major factors that determine an object's orbital velocity around a planet.
Planet mass and orbital distance. (Do not accept "Mass")
The derivative of the angular displacement with respect to time.
Angular Velocity (omega)
The relationship between linear and angular momentum.
L = r x p
The name of the "guest" student we had from Mr. B's classroom.
Grandma Chase (Do not accept "Grandma")
The relationship between these two forces relates the centripetal force and the force that keeps a person from falling in a gravitron carnival ride as the floor is taken away.
Friction and Normal force
This is another name for Kepler's 2nd Law.
The Law of Equal Areas
The name for the length along which a force is applied to induce a torque.
The Moment Arm
For a system of two objects that collide, if there are no external forces, these two quantities are conserved.
Momentum and Angular Momentum
Dr. Culbreth's favorite Bollywood Actor
Shah Rukh Khan
The speed of an object of mass m on a frictionless banked turn of radius r and angle theta.
v = Sqrt(rg tan(theta))
R = 2GM/c2
The Schwarzschild Radius
The tension required to keep an object in static equilibrium if a string is attached to the end of a meter stick of mass m and makes an angle theta with the meter stick.
mg / 2sin(theta)
The translational velocity in terms of the angular velocity for a wheel of mass M and radius R rolls on a level surface without slipping.
v = R(omega)
The reason Dr. Culbreth is teaching, according to the sign on his desk, is because this job was taken.
Cat herder
The G force value for the normal force on an object at the bottom of a 10m radius circular loop if the object is able to barely able to make it over the loop.
6 Gs
The equation for the period of oscillation of an object in orbit around a planet of mass M and radius R if it is distance r from the surface of that planet.
T = Sqrt(4pi2(r+R)3 / GM)
The moment of inertia for a system which contains a uniform stick of mass M and length L attached to a fulcrum at one end and a particle of mass 2M attached to the end of the stick opposite that of the fulcrum.
7/3 ML2
The angular momentum for a particle of mass m with respect to the origin of a coordinate plane if the particle is at point (x,a) and is moving with constant speed, v, toward the vertical axis along the line y=a where a is a constant.
L = mva
