Correctly to Pass
Precision - Answer how close a group of measurements are to each other
accuracy - Answer How close a measurement is to the true value
metric system - Answer a system of measurement based on the number 10
scientific notation - Answer Expresses any number as a number between 1-10 (known as a coefficient)
multiplied by 10 raised to a power (exponent)
scientific method - Answer series of steps followed to solve problems including collecting data,
formulating a hypothesis, testing the hypothesis, and stating conclusions
Speed - Answer distance divided by time
Distance - Answer how far an object moves
Acceleration - Answer the rate of change in velocity
velocity - Answer the speed of an object in a particular direction
displacement - Answer the change in position of an object
wave - Answer a repeating disturbance or movement that transfers energy through matter or space
transverse wave - Answer a wave that moves the medium in a direction perpendicular to the direction in
which the wave travels
, longitudinal wave - Answer a wave in which the vibration of the medium is parallel to the direction the
wave travels
inertia - Answer the tendency of a body to maintain is state of rest or uniform motion unless acted upon
by an external force
frequency - Answer the number of complete wavelengths that pass a point in a given time (for example,
per second)
wavelength - Answer The distance from any point on a wave to an identical point on the next wave
pitch - Answer An indication of how high or low a sound is, which is primarily determined by the
frequency of the sound wave
amplitude - Answer (physics) the maximum displacement of a periodic wave
light energy - Answer Energy that is made of electromagnetic radiation that travels in waves.
sound wave - Answer a longitudinal wave that is caused by vibrations and that travels through a material
medium
medium - Answer the material through which a wave travels
doppler effect - Answer change in the apparent frequency of a wave as observer and source move
toward or away from each other
Electromagnetic spectrum - Answer arrangement of electromagnetic radiation--including radio waves,
visible light from the Sun, gamma rays, X rays, ultraviolet waves, infrared waves, and microwaves--
according to their wavelengths
reflection - Answer the bouncing back of a ray of light, sound, or heat when the ray hits a surface that it
does not go through
