Quick student answer

What should you know about (HT only) Explain how crumple zones increase collision time and absorb energy?

Direct answer

In Physics, this page helps you answer questions about (HT only) Explain how crumple zones increase collision time and absorb energy within Momentum. Focus on the key process, correct scientific terms, and how the idea links to exam-style questions. Key terms to check are Crumple Zone and Collision Time.

Key terms

  • Crumple Zone: A structural feature in vehicles designed to absorb energy during a collision, increasing the time taken for the impact.
  • Collision Time: The duration over which a collision occurs, which can affect the force experienced by occupants in a vehicle.

Common trap

Crumple Zones and Energy Absorption: Explain that crumple zones increase the time over which the collision occurs, allowing them to absorb energy and reduce the force on passengers.
