Movin' on through
The displacement in a graph showing how quickly I changed my speed with time?
What is the equivalent area under a curve for a velocity vs. time graph?
Energy transformed into when lost in a collision
What is sound, heat or light?
The point where the object acts as though all of its mass is at that point.
What is center of mass?
This has units of N.m2/kg2?
What is Universal Gravitational Constant?
Cannot add mass or energy to the system.
What is an isolated system?
Specific motion makes you feel heavier than you are and your motion in an elevator. It is too apparent.
What is accelerating upwards in an elevator because of apparent weight?
This quantity is not conserved in an inelastic collision.
What is kinetic energy?
The quantity that is conserved when the shape of a spinning object changes as long as there are no external torques.
What is angular momentum?
The direction of the net force on a satellite moving in earth's orbit.
What is pointed towards the center?
A frictionless roller coaster that starts at height 4h will be traveling this much faster than one that starts at height h..
What is twice?
This is reached when an object falling through air is no longer accelerating.
What is terminal velocity?
Specific physical quantity when the cannon bounces back after the cannonball shoots out
What is recoil velocity?
When the fingers curl in the ccw and the thumb points outward
What is the Right Hand rule?
This is measured in N/kg
What is gravitational field strength?
A specific condition on an object occurs when it is moving with constant velocity
Dynamic mechanical equilibrium
This quantity is the area under a force versus time graph and is equal to the change in momentum.
What is Impulse (J)?
The best angle (relative to the lever arm) to maximize the torque produced by a force.
What is 90 or 270 degrees?
This is sqrt(GM/r)
What is the orbital velocity of an object?
Force and displacement are this to each other when no work is done.
What is perpendicular?
An object reaching here with maximum velocity as it swings by.
What is the equilibrium position?
This happens when one mass elastically collides with another identical mass at rest
The speed of colliding mass pre-collision is the same as that of the other mass post-collision
As the spinning rate increases by two, this quadruples as long as the shape of an object is held constant.
What is rotational kinetic energy?
The gravitational force changes by this much if you are standing at a distance two times the radius of the earth from the Earth's surface.
What is 1/9?
this has dimensions of is M1L2T-3
What is power?
