Chapter Content
Located at front and rear, absorb minor impact and protect against collisions.
Detailed Explanation
Bumpers are located at both the front and rear of the vehicle and are designed to absorb minor impacts and reduce damage during collisions. They play a crucial role in protecting both the car itself and the occupants inside; they are designed to crumple in a way that dissipates energy from an impact.
Examples & Analogies
You can think of bumpers like the padding in a helmet. Just as padding absorbs the impact in case of a fall to protect the head, bumpers absorb collision forces to safeguard the car and its passengers.

Chapter Content
Shield wheels and lower body from mud and debris.
Detailed Explanation
Fenders, or mudguards, are located over the wheels of the car. Their main purpose is to shield the lower part of the vehicle from mud, debris, and water that can be kicked up by the tires while driving. This helps to keep the car clean and improves visibility by preventing debris from being flung onto the windows.
Examples & Analogies
Imagine wearing a raincoat while walking in the rain. Just as the coat protects you from getting wet, fenders help protect the car's body from dirt and moisture.
