.......that the object or vehicle is moving at a constant speed |
|
|
A
Units for speed could be…. |
B
........metres per second or miles per hour |
|
|
A
Velocity is different to speed because….. |
B
..........velocity has a direction (e.g. 200m/s north). |
|
|
A
Speed cameras take….. |
B
.........two pictures and look at the distance travelled between them |
|
|
A
To calculate speed….. |
B
.......divide distance travelled by time taken |
|
|
A
The speed of a car that travels 200m in 10 seconds is…. |
B
........20 metres per second. |
|
|
A
On a distance-time graph, a horizontal line shows… |
B
......that the object or vehicle is stationary |
|
|
A

|
|
A
To calculate acceleration…. |
B
........divide the change in speed by time. |
|
|
A
Units for acceleration could be |

|
|
C
The equation linking force acceleration and mass is…. |
D
Force = mass x acceleration |
|
|
C
If you have two identical cars the car whose engine gives the greatest force…. |
D
......will accelerate faster |
