What is meant by acceleration?
When an object moves faster and faster.
What type of graph is this?
A distance-time graph
Use the distance time graph to calculate the average speed of Lucy over her whole journey?
Speed = Distance ÷ Time
Speed = 4000m ÷ 45 minutes (x60 to turn into s)
Speed = 4000m ÷ 2700
Speed = 1.48 m/s
What does the distance-time graph below represent?
An object that is accelerating.
At which 2 points in time did the person stop according to the distance-time graph?
At 10 minutes and 30 minutes.
Whenever the line goes flat the object is staitonary.
The graph shows part of a distance-time graph. Which line represents an object moving at a medium speed?
The red line because its steepness is in the middle.
The graph shows part of a distance-time graph. Which line represents an object moving at the highest speed?
The green line because it is the most steep.
The graph shows part of a distance-time graph. Which line represents an object moving at a slow speed?
The purple line because it is the least steep.
