What changes when a force acts on a object?
The momentum of the object changes.
1 of 8
What can sometimes happen the longer it takes to change?
The smaller the force that acts is.
2 of 8
What sometimes happens in a collision?
The momentum of an object becomes zero as the object comes to rest.
3 of 8
What is imapact time?
Time taken for a collision to take place.
4 of 8
What happens if the impact time is short?
The forces on the object are large.
5 of 8
What happens if the impact time is increased?
The force becomes less.
6 of 8
What are crumple zones?
Region of the car designed to crumple to reduce forces on passengers.
7 of 8
How do crumple zones work?
They increase the impact time so reduce the force on the car and people in it.
