Newtons Laws and Car Safety

What is Newton's First Law of Motion?

• Force equals mass times acceleration.

• An object in motion stays in motion unless acted upon by an external force.

• For every action, there is an equal and opposite reaction.

• Energy cannot be created or destroyed.

Which safety feature in cars is primarily designed to protect passengers during a collision?

• Engine

• Seatbelt

• Tires

• Windshield

According to Newton's Second Law, if a car accelerates faster, what must happen to the force applied?

• It decreases.

• It remains constant.

• It increases.

• It becomes irrelevant.

Which of the following features uses sensors to detect potential collisions?

• Anti-lock braking system

• Airbags

• Collision avoidance systems

• Seat adjusters

Scenario 1: During a car crash, a passenger who is not wearing a seatbelt moves forward with the car's initial speed. When the car suddenly stops, the passenger continues moving due to inertia. Question: Explain how Newton's First Law of Motion applies to this scenario and why wearing a seatbelt is crucial.

Scenario 2: A new car model is designed with advanced crumple zones that deform upon impact. Engineers test this feature by simulating a crash at different speeds. Question: Discuss how Newton's Second Law relates to the design of crumple zones and their effectiveness at various speeds.
