What is the physics behind why helmets work?

When a bike helmet breaks, it’s absorbing what’s called “impulse”—a secondary effect of an initial force. Impulse, which gives objects momentum, is what transmits kinetic energy through a system. It takes into account not just force, but also how long that force was applied.

How do helmets absorb energy?

Helmets designed to handle major crash energy generally contain a layer of crushable foam.

What do helmets do in Newton’s first law?

Once the rider’s head hits the concrete, his brain, cushioned only by a very thin layer of cerebrospinal fluid, will also follow Newton’s law until it presses up against the skull. A good helmet can act to absorb and distribute the force of the impact, and thus, lessen the impact on the rider’s head.

How do helmets protect you?
