Really Smart



Cars are vehicles with four wheels that are powered by an engine. They are used for transportation, freight, and recreation. The first cars were invented in the late 19th century and were powered by steam engines. Since then, cars have become a major mode of transportation, with over 1.2 billion cars on the roads around the world. Cars have different parts and systems that work together to make them operate. The engine is the power source, burning fuel to produce energy that is used to move the car. The transmission changes the power output of the engine to the drive wheels, allowing the car to move at different speeds. The suspension system absorbs bumps and shocks, making the ride smoother. Other components include the brakes, steering, and electrical system. Cars are also designed with safety systems to protect passengers in the event of a crash. Airbags, seatbelts, and crumple zones are all designed to reduce the impact of a collision. Fun Fact: The Tesla Model S has the longest range of any electric car, with a range of over 400 miles on a single charge.
