A distance-time graph which is a straight line indicates constant speed.
In constant speed, the object does not speed up or slow down. The acceleration is zero.

A graph that curves on a distance-time graph shows that the object is accelerating

Speed = Distance ÷ Time D_ S T
Example: A car travels 300km in 6 hours. What is the speed of the car?

Speed = distance ÷ timeSpeed = 300km ÷ 6 hoursSpeed = 50km/hr

Describe the motion of the object as shown in the
graph.
From 0-8 sec, constant speed:(25 m/sec);From 8-12 sec, no motion;From 12-16 sec, acceleration;From 16-20 sec, constant speed

Using the distance-time graph from the last frame, draw a speed time graph. First fill in the table below:
Average Speed (m/s) Time (sec)
____ 0 to 8____ 8 to 12____ 12 to 2025
0
37.5

Constant speed will be a horizontal line on a speed time graph.
If the speed decreases, the line will slant down.
If the speed increases, the line will slant up.

Change in velocity◦Can be change in speed or direction
◦Acceleration = ∆V/ ∆T

A roller coaster’s velocity at the top of a hill is 10m/s. Two seconds later it reaches the bottom of the hill with a velocity of 26m/s. What is the acceleration of the roller coaster?
![Page 19: On your paper, graph the following: D (m) T (sec) 00 57 57 10 14 15 21](https://reader036.vdocument.in/reader036/viewer/2022062318/5515a703550346a1418b61fc/html5/thumbnails/19.jpg)
Acceleration = ∆V/ ∆Ta = 26m/s – 10m/s
2 sa = 16m/s
2sa = 8m/s/s or 8m/s2

Negative acceleration Example: A car slows from 60mi/hr to
20mi/hr in 4 seconds. What is its acceleration?
Acceleration = ∆V/ ∆T Acceleration = Vf – Vi
t a = 20mi/hr – 60mi/hr
4 sa = -40mi/hr
4sa = -10mi/hr/s
