Distance time graphs

2. DISTANCE-TIME
GRAPHS
A straight line shows an object moving at a constant speed!
The steeper the line, the faster the object is moving!

Curved lines show if
an object is
accelerating or
decelerating!
The steeper the line
gets the faster the
object is moving!

MAN WALKING A CAT
1. What is the speed of the
man during the first three
seconds?
2. What is the man doing
between 3 and 5 seconds?
3. Calculate the speed of the
man between 5 and 7 seconds.
4. What is the total distance
that he has moved?
5. Calculate the average
speed for the whole journey.
• 1. 12/3 = 4 m/s

6. Draw a distance-time graph showing your
journey to school!
Try to include different gradients to show
different speeds. Remember – steep slope is
fast, gentle slope slow!!
Try to include rough distances and times at
key points on your graph.
Sketch a distance -time graph for a parachute jump!
Think carefully!!!!

7. Describe the motion of the jogger in each section of the graph!
