- A bolometer, a device to convert electromagnetic radiation and the momentum of energetic particles to thermal energy which in turn is easily measured
- A kinetic-energy absorbing medium, sometimes called a crash pit or runaway truck ramp
- A shock absorber, a device to dampen spring rebound by expending work by forcing a fluid through ports, and so converting the mechanical energy to heat
- A material or device to disperse and dissipate impact energy, such as
- a protective helmet for sports, motorcycling or bicycling
