1

What is meant by acceleration?

When an object moves faster and faster.

2

What type of graph is this?

A distance-time graph

3

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

4

What does the distance-time graph below represent?

An object that is accelerating.

5

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.

6

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.

7

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.

8

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.
