I've been told that if I want to lose weight, I can just go to Mars? Is this true? Please explain.
It is true that when you go to Mars, your weight will be less because there is less gravitational force exerted on you. However, if no mass is gained or lost, you will return your normal weight when you come back to Earth.

Why are airbags in cars important?
Because if the car were to suddenly stop, your body would continue in moving until an unbalanced force acted on it. In this case, it's better to have an airbag push on your face than the windshield.
