The Science Behind Car Crashes

What is the property of matter that causes it to resist any change in its state of motion?

• Momentum

• Friction

• Inertia

• Gravity

According to Newton's First Law of Motion, what happens to a body at rest?

• It decelerates

• It accelerates

• It remains at rest

• It starts moving

What is the formula for Newton's Second Law of Motion?

• p=mv

• E=mc^2

• F=ma

• a=F/m

What is the product of an object's mass and its velocity called?

• Force

• Impulse

• Energy

• Momentum

Why are seatbelts important in a car crash?

• They reduce the car's mass

• They increase the car's speed

• They help slow down the occupant with the car

• They prevent the car from crumpling

What is a 'g' in the context of car crashes?

• A unit of force

• A unit of acceleration or deceleration

• A unit of velocity

• A unit of mass

What happens to the momentum of two identical cars traveling at 30 mph when they collide head-on?

• It cancels out

• It triples

• It doubles

• It remains the same

What is the formula for kinetic energy?

• KE = ma

• KE = mv

• KE = Fd

• KE = 1/2 mv^2

What is the primary advantage of a larger, heavier car in a crash with another vehicle?

• Better fuel efficiency

• Higher speed

• More protection for occupants

• Less inertia

What is the purpose of crumple zones in vehicles?

• To absorb crash forces and protect occupants

• To improve fuel efficiency

• To increase the car's speed

• To reduce the car's weight
