Question

To move at the same speed, a car with a flat face and another with a streamlined body will require different amounts of force from the engine. The engine of the streamline bodied car will:

• A. Exert less force
• B. Exert more force
• C. Exert zero force
• D. None of these

Answer 1

The correct option is A Exert less force

A car with streamlined body suffers less air friction while moving. And the car with a flat face will suffer higher air friction. As a result, the car with streamlined body will require less force from the engine to maintain the same speed.
