1
Q

kinematics

A

the study of motions

2
Q

motion

A

a change in an object’s locations as measured by a particular observer

3
Q

distance (d)

A

the total length of the path travelled by an objects in motion SCALAR QUANTITY
- how far did you go?

4
Q

direction

A

the line an object moves along from a particular starting point (north, south, east, west1-

5
Q

scalar quantity

A

has magnitude (size) only

6
Q

vector quantity

A

has magnitude (size) and also direction (symbol has arrow above it)

7
Q

position

A

an object’s location relative to a reference point

8
Q

displacement

A

change in position VECTOR QUANTITY

- where are you, relative to where you started?

9
Q

speed equation

A

speed = distance/time SCALAR

10
Q

velocity equation

A

velocity = displacement/time

11
Q

uniform motion

A

when the velocity is constant

12
Q

how to get displacement from velocity vs time (uniform motion)

A

displacement = (velocity)(time) [area from line to x-axis]

13
Q

uniform acceleration

A

how quickly an objects’ velocity changes over time (rate of change of velocity) [m/s^2]

14
Q

if the line moves AWAY from x axis…

A

it is speeding up

15
Q

if the line moves TOWARDS from x axis…

A

it is slowing down

16
Q

if the line is ABOVE the x axis…

A

it is moving up

17
Q

if the line is BELOW the x axis…

A

it is moving down

18
Q

if the line is AT x…

A

it remains still/stops
