Torque
Torque is equal to the product of these two quantities.
What are distance and force?
The rate of change of the angle of an object.
What is angular speed/velocity?
Rotational kinetic energy is measured in these units.
What are joules?
What are newton-seconds (newtons times seconds)
The original Star Wars film was released in this year.
What is 1977?
The torque on an object is equal to the distance from the pivot point and this component of the applied force.
What is perpendicular?
The rate of change of angular speed.
What is angular acceleration?
What is 1/2 times I times omega squared?
This is the equation for angular momentum.
What is I times omega?
The first Death Star was destroyed in orbit above this planet.
What is Yavin?
This law states that the net torque on an object is equal to the product of the object's rotational inertia and its angular acceleration.
What is Newton's Second Law for rotation?
This is the acceleration that always points toward the center of the circle, keeping the object moving in a circular trajectory.
What is centripetal acceleration?
This theorem defines the work done on an object moving in a circular path as being equal to the change in the object's rotational kinetic energy.
What is the work--energy theorem?
This principle states that if no external torque acts on a system, the total angular momentum of the system remains constant.
What is conservation of angular momentum?
This was Paul Atreides Fremen name.
Who is Muad'dib?
This condition occurs when the sum of all torques acting on an object equals zero, resulting in no angular acceleration.
What is rotational equilibrium?
This property of an object describes its resistance to rotational motion and depends on both the object's mass and the distribution of that mass relative to the axis of rotation.
What is rotational inertia (or moment of inertia)
If the angular velocity of an object is doubled, the rotational kinetic energy will increase by this factor.
What is four?
If angular momentum is conserved, and the radius of the circular trajectory of an object is decreased, its angular velocity will do this.
What is increase?
One Ring of Power was forged by Sauron to control all the others. This many rings were forged for the kings of the elves.
What is 3?
When an object is rolling down a hill, this force produces the torque required to make the object spin.
What is friction?
Between a solid cylinder and a hollow cylinder of the same mass and diameter, this one will have the greater moment of inertia.
What is a hollow cylinder?
Objects with a lower __________ will roll down a hill faster because it is easier to make them spin.
What is rotational inertia (or moment of inertia)?
If the radius of rotation of an object is cut in half, the angular velocity will increase by this factor.
What is 2?
There were this many members of the Fellowship of the Ring when they departed from Rivendell.
What is nine?
