9. Converting Speed-Time Graphs to Distance-Time Graphs
Success Criteria
Your learning has been successful if you can do the following:
Define acceleration and its units.
Calculate acceleration from speed and time measurements.
Vocabulary
Learn these so you can communicate this concept well.
Average speed: Calculated by the total distance travelled divided by the total time taken for the journey.
Gradient / slope: How steep a line on a graph is.
Speed: How fast an object is moving.
Velocity: Similar to speed, but also tells us the direction in which an object is moving. It includes both speed and direction of motion.
Do Now:
Collect and complete this small 'Do Now'. Then glue into your SciPAD page 11. Use your commonsense when glueing - don't glue straight on-top of words!
Find some space on page 15 of your PESS1.2 SciPAD,
and answer the following questions:
What does each letter in CUTLASS stand for?
How are Distance Time Graphs converted to Speed-Time Graphs and vice versa
A ticker-timer tape can be converted into a graph by cutting the paper through each dot and gluing the resulting strips side by side.
In the example below, there are five intervals, so cutting through 1-6 dots will give 5 strips. When the strips are placed side to side, the horixontal axis represents time intervals and the vertical axis represents velocity.
