A layer of padding is added to car dashboards because it can reduce some injuries during a collision. How does the padded dashboard make people safer?
Decreases the momentum of a collision
Increases the time of impact in a collision
Decreases the impulse in a collision
Increases the force of impact in a collision
What is an object's change in momentum equal to?
Velocity change of the object
Forces acting on it times its velocity
Impulse acting on it
Force acting on it
