In the image two kids run into each other holding exercise balls. Why are they using exercise balls?

• The exercise ball helps each kid accelerate more.

• The exercise ball helps reduce the force of impact each kid feels.

• The exercise ball reduces each kid's mass.

• The excerise ball prevents the kids from experiencing any force.

While car airbags help reduce injury. Sometimes airbags still cause injury to the face or nose. Why does this happen.

• The air bag has a lot of momentum and momentum always causes injury to a person.

• The airbag has more mass than the person, and so applies more force, because F=ma.

• When the person's face hits the airbag, the airbags applies and equal force back to the person.
