Circular Motion
This is the direction of centripetal acceleration & force.
What is inward (towards the center)?
This describes the direction of the force of gravity existing between all objects.
What is attractive?
Torque is maximized when the force acts at this angle to the lever.
What is 90 degrees?
Power
What is a Watt?
“It's not that I'm so smart, it's just that I stay with problems longer.”
Who was Albert Einstein?
This force provides the centripetal force allowing objects to orbit in outer space?
What is the gravitational force?
This relationship exists between Gravitational Force and the distance between masses.
What is inverse squared relationship?
The translational speed of an object that is rolling without slipping.
v=ωr
Energy
What is a Joule?
“I can calculate the motion of heavenly bodies but not the madness of people.”
Who was Isaac Newton?
This is the direction of velocity for an object moving in a circle.
What is tangent to the circle?
The force of gravity effectively acts upon this location for any object.
What is the center of mass/gravity?
The Moment of Inertia of a rotating object depends upon this.
What is the distribution of mass about the objects axis of rotation?
Moment of Inertia
What are kg∙m2?
"Measure what can be measured, and make measurable what cannot be measured."
Who was Galileo?
TRUE OR FALSE:
An object moving at a constant speed in a circle is not accelerating.
What is False?
The maximum allowable gravitational potential energy between masses. (According to the equation)
What is zero?
The change in angular momentum resulting from a figure skater bringing their arms inward during a spin.
What is no change to momentum?
Torque
What are N∙m?
"Now I am become death, the destroyer of worlds"
Who was J Robert Oppenheimer?
The resulting change in centripetal acceleration when velocity is tripled.
What is nonupled?
Do this to Newton’s Universal Law of Gravitation to get the Potential Energy function.
What is take the integral with respect to position?
A solid cylinder and ring of the same mass and radius are released from rest at the top of a ramp. Which will have more kinetic energy at the bottom?
Equal
Impulse
What are kg∙m/s OR N∙s?
“Those who are not shocked when they first come across quantum theory cannot possibly have understood it.”
Who was Niels Bohr?
