One-Dimensional Kinematics Flashcards

Flashcards about One-Dimensional Kinematics

__: straight line, to the left or to the right, up or down, east or west, etc.

One-dimension

__: the study of motion using words, numbers, graphs and equations

Kinematics

__ - A quantity that has only a magnitude (number or value)

Scalar

__ - A quantity that has both a magnitude and a direction

Vector

__ – a scalar quantity that refers to how much ground an object has covered during its motion

Distance

__ - a vector quantity that refers to how far your ending point is from your starting point

Displacement

__ is the ratio of distance and time (always positive)

Speed

avg speed = distance traveled/ __

time

__ is the ratio of displacement and time (can be + or -)

Velocity

avg velocity = displacement/ __, vavg =∆x/t

time

__ Velocity - the speed at any given instant in time.

Instantaneous

__ Velocity - the total displacement covered over the total time

Average

__: The change in an object's motion

Acceleration

An object is in __ when the only force acting on it is gravity.

Free Fall

All unsupported objects fall towards earth with the same __.

acceleration

The __ due to gravity is - 9.8 m/s2
