Motors

For the past couple of weeks, my 14-year old car has been making noises that have progressively been getting worse. Last night, my dad drove it home to see what was wrong, and actually had to pull on the side of the road to make sure nothing was falling out of my car. This is because, he suspects the motor (engine) holder - which holds the motor in place - is broken. As a result, he thinks my engine is not being held in place any longer, which could be very dangerous if it breaks other things while rolling around under my car. I thought this related to physics because we just learned how a simple motor can be made, with just a wire, a magnet and a battery. Since the magnet's magnetic force exerts a torque on the coil made with wire, the coil will spin due to the the torque and the current that comes from the battery. This is basically what should be happening underneath my car, inside the engine holder. However, if the engine holder is broken (as mine is) the motor that is spinning due to the torque and energy source is free to roll wherever it would like to. Therefore, my dad is forbidding me to drive my car until it gets fixed.
