What is speed? |
Speed tells us how fast something is going |
|
|
|

What are balanced forces? |
Balanced forces are forces which are the same size but work in opposite directions. |
|

|
When does air resistance increase? |
Air resistance increases as the speed increases, so cars use up more fuel when they are traveling fast |
|
|
|
When does air resistance increase? |

|
|
|
When does air resistance increase? |
Air resistance increases as the speed increases, so cars use up more fuel when they are traveling fast. |
|
|
|
What causes air resistance? |
It is caused by air particles hitting the moving object. |
|
|

|
|
|
What causes air resistance? |
It is caused by air particles hitting the moving object. |
|
|
|
What do these particles cause? |
The particles transfer energy to the object, which is why objects moving through air can get hot. |
