EFFECT OF ACCELERATING A CAR WHEN GEAR LEVER IS AT PARK

When car lever is at packed , accelerating the car to high RPM (revolution per minute) might have bad effect on the car.
Car engine is designed to move the car from one place to another when the engine is running, therefore converting the mechanical energy to kinetic energy. When the gear lever is at parked at the same time the car engine is running, the mechanical energy is been converted to potential energy, if one notice , accelerating the car when the gear lever is at park will only increase the RPM, that is,the speed of rotation of crank shaft , no distance covered. At very high RPM,the fan screwed to from of the engine might flew off with high velocity, it will damage the radiator by hitting it very hard , because for some cars, the fan is been driven by pulley from the engine therefore the higher the speed of the engine,the higher the speed of fan too. It might also damage the water pump because the fluid will be circulating at high pressure since the water pump is also driven by pulley.
