100
What is the acceleration of gravity?
-9.81 m/s^2
100
What is Newton’s first law of motion?
Objects in motion stay in motion unless acted upon by an outside force.
100
What is Energy?
The ability to do work.
100
What is an elastic collision?
All momentum is transferred between the objects in question and they bounce off of eachother.
100
What is a node?
A point in a standing wave that does not move.
200
What is Displacement?
A change of position in a certain direction.
200
What is a free body diagram?
An illustration used to represent applied forces using arrows.
200
What is gravitational potential energy?
mass x gravity x height
200
What is an inelastic collision?
Momentum is transferred elsewhere (such as to sound) and objects stick together.
200
What is the frequency (in Hz or 1/seconds) x wavelength (in m)?
or
What is sqrt( Tension / mass/length )?
Speed of sound (in m/s).
300
What is displacement/time?
The equation for velocity.
300
What is equilibrium?
The state in which the net force on an object is zero.
300
What is elastic potential energy?
½ kx^2
300
What is Impulse?
The time it takes for a force to be applied/removed (=Force in a direction x change in time).
300
What is periodic motion?
Sinusoidal behavior, oscillates over a period of time.
400
What is projectile motion?
The curved path that an object follows when thrown.
400
What is normal force?
The force that is perpendicular to the surface an object is contacting.
400
What is Power?
work / change in time
400
What is the equation for Centripetal Force?
(mass x tangential velocity ^2 ) / radius of the circle
400
What is Hooke's Law?
Fs = -kx
500
What is the vertical vector equation?
v = vi sin(θ)
500
What is f(friction) = μ(coefficient of friction) times N(normal force)?
The equation to measure friction.
500
What is the Work kinetic energy theorem?
Wnet = ΔKE
500
What is Newton’s Law of Universal Gravitation?
F = G( M1 M2 / d^2)
500
What is the frequency of overtone N?
fn = N ( Vsound / 2L )
