Kinematics Vocab Pt1 Flashcards
Kinematics
How things move
Distance
Length between objects
Displacement
Change in position of an object
Velocity
How fast something moves from one thing to another
Speed
How fast something moves
Vector
Arrows consisting of magnitude and direction
Scalar
Physical quantity only described by magnitude
Projectile
An object driven or projected forward
Force
The push or pull on an object with mass causes it to change its velocity
Conservation of momentum
when two objects collide in a closed system
Length-meter
Measurement of distance in meters
Time-second
the measure of a change in a physical quantity or a magnitude used to quantify the duration of events
Amount of substance (mole)
SI unit of amount of substance
Electric current-ampere
the flow of electrical charge carriers like electrons
Temperature-kelvin
describes the average kinetic energy of molecules within a material or system
Luminous intensity-candela
A way to describe how much light is Emmettd from a source in a specific direction
Acceleration
rate at which velocity changes with time, in terms of both speed and direction
Average speed
add up the total distance traveled. Then divide this by the total time spent traveling
Elapsed time
the amount of time that passes from the start of an event to the finish of the event
Free fall
the motion of an object where gravity is the only force acting upon it
Instantaneous speed
the speed of an object at a particular moment in time
Rate
How fast something is changing in relation to something else
Relative
the motion of one object with respect to another object
Component
Each part of a two-dimensional vector
