the branch of applied mathematical dealing with motion and forces
mechanics

measures the positions, speed or velocity, and acceleration of objects
kinematics

the branch of mechanics concerned with the motion of bodies under the action of forces
dynamics

the branch of mechanics concerned with bodies at rest and forces in equilibrium
statics

a pause or break in activity
interval

any measurable quantity that can be completely described with a single piece of information is a scalar quantity;
having only magnitude, not direction
scalar

a quantity having direction as well as magnitude
vector

the amount of space between two things or people
distance

the moving of something from its place or position
displacement

the great size or extent of something
magnitude


physics, velocity is the rate of change of displacement
average speed

the rate of displacement;the speed of something in a given direction
velocity

increase in the rate of speed of something
acceleration

a set of connected things or part forming a complex whole
system

can slow, stop or reverse the original positive velocity
negative acceleration

equal to the distance traveled
speed

the total distance divided by the total time
average speed

the actual speed at any given moment (basically the speedometer)
instantaneous speed

can be a scalar or vector;
the rate of change of speed or velocity over time
acceleration

vectors are drawn as
lines

requires 2 pieces of information: a scalar for a magnitude and a direction
vector

velocity vs. speed; a measurable quantity that has both a scalar value and a direction associated with it
vector

an entity consisting of one or more parts that logically belong
physical system

the geometric space containing the point of reference
frame of reference, or reference frame

an imaginary line marked off in distance units
coordinate axis

physicists split mechanics into 3 parts:
kinematics, dynamics, statics
