If an electric car is moving downhill with its motor disconnected from the electrical source, the acceleration of the car increases according to Newton’s laws of motion. Explain this motion in terms of energy.
What will be an ideal response?
Let the incline of the hill be theta. Then, if the car acceleration is ‘a’, the
following Newton’s equations hold:
Since the acceleration is positive and there is no form of energy drain on the
system, the energy of the system increases.
