Unit 2 Uniform Motion

What is the slope of this graph?

0 slope = object is not moving

Velocity vs time graph

All flat lines = constant velocity

Displacement is another term for ___________________

Change in Position

Distance travelled

How far did the object travel

Distance Traveled is always _______________________

Positive

What is the slope of this graph?

Positive Slope = object is moving to the right

velocity

Speed in a given direction

position vs time graph

a graph that show the the change of an object over a given time

motion diagram

a series of images showing the positions of a moving object at equal time intervals

velocity vs time graphs for uniform motion

always have flat lines = constant

Δ =

change

Change in position=

displacement

larger steep line (large slope)

faster the object

Motion

how objects move not why they move

negative direction of travel

moving to the left

positive direction of travel

moving to the right

flat line=

no slope

x=

position

Xf

position final

Xi

position initial

smaller steep (small slope)

slower the object

Object starts at __________, moves to the _____________

starts at 0 and moves to the right (positive direction)

Slope=

steepness of a line

t=

time

constant speed

uniform motion

v=

velocity (m/s)

slope of a position vs time graph

velocity of the object

Position

where an object is is relative to "zero", another object, or a mark

Formula for slope

y2-y1/x2-x1

Formula for "Distance Traveled"

|Δx| = |Xfinal -Xinitial|

Formula for "Change in Position"

Δx=Xfinal -Xinitial
