INTERPRETING VELOCITY VS TIME GRAPHS HONORS PHYSICS
Slide 2
NOT POSITION VS TIME GRAPHS! Do not get them confused! They
will both be on the EOC. It is up to you to read the question and
the graph and make sure you are analyzing the correct type of
graph!
Slide 3
VELOCITY VS TIME GRAPHS Tell you the velocity of an object at
any point in time. Constant - 4 m/s Decreasing 4 to 0 m/s
Increasing 0 to 4 m/s What is the velocity of the object at 1 a
time of 1 second? What is the velocity of the object at 1 a time of
6 seconds?

FINDING ACCELERATION Remember acceleration is a change in
velocity If the velocity of the object is changing on the graph, it
is accelerating. The acceleration of the object is equal to the
slope of the velocity vs time graph!!!
Slide 11
CALCULATING ACCELERATION
Slide 12
FIND THE ACCELERATION
Slide 13
FINDING DISPLACEMENT FROM A V-T GRAPH The displacement of an
object is equal to the area under the velocity vs time graph. Area
= Displacement
Slide 14
FINDING DISPLACEMENT FROM A V-T GRAPH How do we find the area
under this graph? Base = 5 secondsHeight = 20 m/s Displacement = 50
m Area = bxh
