Waves & Sounds
the distance from, for instance, one peak to the next peak on the displacement versus position graph
What is wavelength.
What is energy?
What is the capacity to do work.
Where is Ms. U from?
What is Brownsville, TX
a disturbance that carries energy from one place to another.
What is a wave.
What is the SI unit to measure energy?
What is Joules (J)
What is Newtons second law of motion and it's equation?
What is the force exerted by a moving object is equal to its mass times acceleration in the direction it is pushed. F=ma.
Ms. U's favorite hobby
What is dancing
require a medium (such as water, air, or string) through which to travel
What is mechanical waves.
What is the formula for kinetic energy and its variables?
What is KE=1/2mv^2
KE= kinetic energy
m=mass
v=velocity
Gravity on Earth is measured as...
What is 9.81 m/s2 (10 m/s^2 in this class)
What is Newton's third law (bonus points if you know the equation)?
What is for every action there is an equal and opposite reaction.
FA=-FB
(FA= force exerted by the object in one direction)
(-FB= force exerted by the second object on the first but in opposite direction)
How many siblings does Ms. U have?
3; two sisters one brother
do not need a medium through which to travel, and thus can travel through a vacuum
What is sound waves.
What is the formula for potential energy?
What is PE=mgh
PE=potential energy
m=mass
g=acceleration due to gravity
h=height of the object
distance traveled/time elapsed
What is speed
What is an unbalanced force?
What is when two unequal forces act on an object from opposite sides, resulting in a net force.
What philosophy/style of life does Ms. U align with?
What is Buddhism and mindfulness
exhibits wave-particle duality, sometimes acting as a wave and sometimes as a particle
What is matter wave.
How do you find mechanical energy?
What is ME=KE+PE
Define acceleration with respect to velocity.
What is acceleration = time rate of change of velocity = derivative of velocity with respect to time. (a=dv/dt)
What is the net force of a balanced object?
What is net force zero
Where did Ms. U graduate college and what did she major in?
What is UTSA with a degree in Medical Humanities.
