1. The resistance occurring when one surface or object moves against another. B1 formal scientific

   A physical force that opposes the relative motion of two contacting surfaces, converting kinetic energy into heat and often resulting in wear. It is a fundamental concept in mechanics and a key factor in engineering applications such as brakes and tires.

   • The rough surface created more force opposing motion, slowing the sled.
   • Engineers test tire compounds to reduce the opposing force on the track.
   • Lubricants are designed to minimize the resistance between moving machine parts.
   • Without enough grip from the opposing force, the car skidded on the icy road.
   • The brakes use this opposing force to convert motion into heat and stop the vehicle.
