W |
What is the difference in speed between a car travelling a 30 m/s and a lorry travelling at 20 m/s? => 10 m/s
How did you work this out? => 30 take away 20
This is the relative motion between the car and the lorry. |
|
What is the difference in speed between a car travelling a 30 m/s and a lorry travelling at 20 m/s?
How did you work this out?
What does this difference in speed show? |

T |
The relative motion is the 'motion' (movement) of one object measured 'relative' (from) another. |
|
What is meant by 'relative motion'? |
|
|
T |
How much further does the car get away from the lorry in one second? => 10 m/s
What if the car starts behind the lorry? => The car would get closer, maybe collided at 10 m/s. |
|
How much further does the car get away from the lorry in one second?
What if the car starts behind the lorry? |
|
|
W |
At what speed would they collide at if they were travelling towards each other? => 50 m/s
How did you work this out? => 30 plus 20 |
|
At what speed would they collide at if they were travelling towards each other?
How did you work this out? |

T |
Velocity is speed in a direction.
A negative velocity is in the opposite direction to a positive one. |
|
What is velocity?
What is negative velocity? |
|
|
W |
If the lorry is travelling at 20 m/s and a car at -30 m/s what speed do they collide at? => 50 m/s
How did you work this out? => 20 take away minus 30 |
|
If the lorry is travelling at 20 m/s and a car at -30 m/s what speed do they collide at?
How did you work this out? |
