Page 1: Diagrams and Motion Graphs.  The slope is equal to the acceleration.  Because we only consider constant acceleration, v/t graphs will always be straight.

Diagrams and Motion Graphs

Page 2: Diagrams and Motion Graphs.  The slope is equal to the acceleration.  Because we only consider constant acceleration, v/t graphs will always be straight.

The slope is equal to the acceleration.

Because we only consider constant acceleration, v/t graphs will always be straight lines.

Velocity vs. time graphs

Page 3: Diagrams and Motion Graphs.  The slope is equal to the acceleration.  Because we only consider constant acceleration, v/t graphs will always be straight.

Velocity vs. time graphs Positive velocity indicates

the object is moving away from the reference point

The x axis means v=0 Green is slower, getting

closer to zero. Purple is speeding up,

moving farther from the x axis.

Negative velocity indicates the object is moving toward the reference point.

Purple line – the negative Velocity “is increasing” at a

faster rate. Green line – the negative

velocity “is decreasing” relative to the reference point.

Velocity vs. time graphs(Acceleration)

When the slope is zero:horizontal line velocity is constant

acceleration is zero

Page 6: Diagrams and Motion Graphs.  The slope is equal to the acceleration.  Because we only consider constant acceleration, v/t graphs will always be straight.

Velocity vs. time graphs

When the slope of the graph is positive:the acceleration

is positive

Page 7: Diagrams and Motion Graphs.  The slope is equal to the acceleration.  Because we only consider constant acceleration, v/t graphs will always be straight.

Velocity vs. time graphs

When the slope of the graph is negative: the acceleration is negative

Page 8: Diagrams and Motion Graphs.  The slope is equal to the acceleration.  Because we only consider constant acceleration, v/t graphs will always be straight.

We cannot determine where an object’s position from a v/t

graph, only its change in position.
