physics vocab linear motion

thermodynamics

the study of heat and its transformation to mechanical energy

heat/pressure/temperature/density

cryogenics

part of physics that studies law temperature phenomena

linear motion

part of physics that studies straight line motion, vertical motion, or horizontal motion

acoustics

part of physics that studies the properties of sound

velocity

the speed of an object and its direction of motion, a vector quality

speed

how fast something moves, the distance an object moves divided by the time it takes, a scalar quality

scalar

quality in physics, such as mass, volume, and time, that can be completely specified by its magnitude and has no direction

vector

quantity in physics that has math magnitude and direction examples are force, velocity, acceleration, torque

optics

the part of physics that studies light, characteristics of light frequencies, and behaviors of light

plasma physics

the part of physics that studied the fourth state of matter of 100,000C, and ionized glass

acceleration

a rate at which an objects velocity changes with time, this is a vector measurement

kinematics

a part of physics that studies motions of objects

delta

triangle, mathematical symbol that means “change in”

positive

vector direction used to represent motion towards the window in class, right, moving up

negative

vector direction used to represent motion towards the door in class, left, and motion moving down

gravity

-9.8m/s² qn acceleration that pulls object in free full in the downward direction towards the center of the earth
