Engineers build cars with special crumple zones. The crumple zone absorbs the impact. This reduces the amount of energy transferred to passengers during a crash.
Collisions happen all around us.
Every day, we see and experience hundreds of collisions. A collision could be as gentle as a puppy licking your face, or as dramatic as a wrecking ball smashing into a building.
Collisions are part of our everyday lives. People drop things which collide with the ground. Drumsticks collide with drums to make sounds.
Sports involve numerous collisions. Think about baseball. The batter tries to collide the bat with the ball. At the instant of impact, the energy transfers from the swinging bat to the ball, which makes it fly.
