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