Engineers are designing a new car and they need to test their ideas by modeling crashes with different types of trucks. They are using a more massive garbage truck for Crash 1 and a less massive pickup truck for Crash 2. The green test car has the same mass in both crashes. Use information from the diagram to answer.

In which crash did the green test car experience a stronger force? How do you know?

During a collision of two billiard balls, which ball experiences the greatest force? Or are they equal? Explain using evidence from the article.

• accurately identifies the changes to each object in a collision

• accurately describes the relationship between force, mass and velocity in a collision

If two objects crash into each other, what can you say is true about the force on each object?

• accurately identifies the changes to each object in a collision

• accurately describes the relationship between force, mass and velocity in a collision

If two objects crash into each other, what can you say is true about the force on each object?

• accurately identifies the changes to each object in a collision

• accurately describes the relationship between force, mass and velocity in a collision

Explain the amount of force each Bumper Car experiences in the crash? What is meant by the arrows?

CFS:

• accurately identifies the changes to each object in a collision

• accurately describes the relationship between force, mass and velocity in a collision

How is the mass related to each car’s acceleration of movement after the collision?
