X-Axis = TIME
Y-Axis = DISTANCE
On a SPEED vs. TIME Graph, which variable is on the X-Axis and which variable is on the Y-Axis?
X-AXIS = TIME
Y-AXIS = SPEED
Distance between starting and ending position
What is DISPLACEMENT?
Speed an object moves in a specific direction
What is VELOCITY?
Increase of Speed
What is Positive Acceleration?
Describe the SLOPE and SPEED in this Distance vs. Time Graph.
Horizontal Line - Object is Stationary.
The formula for calculating speed
What is s=d/t, speed=(distance/time)?
Amy runs 2 miles SOUTH and then turns around and runs 3 miles NORTH.
What's her distance traveled?
5 miles
Pete is driving down 7th street. He drives 150 meters in 18 seconds. Assuming he does not speed up or slow down, what is his speed in meters per second?
What 8.3 M/S ?
(150 m/ 18 sec)
Decrease of SPEED
What is Negative Acceleration?
Describe the SLOPE and SPEED in this Distance vs. Time Graph.
Constant SPEED FORWARD
Describe the SLOPE and SPEED in this Velocity vs. Time Graph.
Increase of Speed = Constant Positive Acceleration!

A train moves from rest to a speed of 25 m/s in 30.0 seconds. What is its acceleration?
What is 0.83 m/s2 ?
25 m/s - 0m/s
____________
30 seconds
Describe the SLOPE and SPEED in this Distance vs. Time Graph.
(DAILY DOUBLE)
CURVED Positive Slope = Constant Acceleration FORWARD
Describe the SLOPE and SPEED in the 2nd part of the journey for this Velocity vs. Time Graph.
Zero Acceleration = Constant SPEED/VELOCITY
(Object is moving at a constant speed.)

What's his distance traveled?
A.
B. 35 km
C. 5 km
The two measurements that you need to calculate speed
What is distance and time?
A roller coaster’s velocity at the top of a hill is 10 m/s. Two seconds later it reaches the bottom of the hill with a velocity of 26 m/s. What was the acceleration of the coaster?
(DAILY DOUBLE)
What is 8 m/s2?
26 m/s - 10m/s
____________
2 seconds
Describe the SLOPE and SPEED in this Distance vs. Time Graph for EACH part of the journey.
Part 1 - Horizontal Line; Stationary
Part 2 - Straight Diagonal; Constant Speed Forward
Part 3 - Horizontal Line; Stationary
Part 4- Straight Diagonal Down; Constant Speed backward
Part 5 - Horizontal Line; Stationary
On this Velocity vs. Time Graph, which Line had the faster POSITIVE acceleration? Line A, B, C, or D?
Line B
Higher the slope = Faster the acceleration
