NEET Physics Kinetic Energy MCQ Question
Consider a diagram showing a car compressing a spring on a frictionless surface. The car, initially moving at 5 m/s, comes to rest after maximum compression of the spring. Which of the following statements correctly describes the energy transformation at maximum compression?
The car's kinetic energy is fully converted into the spring's potential energy.
The car retains some kinetic energy while the spring stores potential energy.
The car's kinetic energy is converted into heat due to friction.
The potential energy of the spring is greater than the initial kinetic energy of the car.
Correct Answer
Detailed Explanation
At maximum compression, the car's kinetic energy is completely converted into potential energy stored in the spring, as per the conservation of mechanical energy.
