Why do two objects fall at the same time?
Hence any two objects that are subject only to the force of gravity will fall with the same acceleration and hence they will hit the ground at the same time. What I think you were missing is that the force F on the two bodies is not the same, but the accelerations are the same.
When to get a second opinion with a car mechanic?
Mechanics know that most people don’t know anything about their cars, so they prey on your fears that you’ll not want to break down on the side of the road. If a mechanic is trying to coerce you in this way, get a second opinion immediately.
What should you do if your mechanic tells you something is too complicated?
Sometimes it is hard to know whether damage happened at the shop unless you examine your car closely. But a mechanic who is trying to pass the buck on damage that couldn’t have happened anywhere other than in the shop is obviously one to avoid. “It’s complicated.” If someone tells you that something is too complicated to understand, run away.
Can a mechanic tell you something about your car?
Nearly everyone has gone to the local shop for routine auto maintenance only to drive away after paying a lot more in unexpected charges. Most mechanics are honest, hardworking people who only want to help you by pointing out problems you may not know about.

Why do mechanics exaggerate how serious a problem is?
Some greedy mechanics will exaggerate how serious a problem is in order to get you to make a repair, even if it doesn’t really have to be fixed right away. You may have a power steering pump, for example, that has started making a minor amount of noise and will need to be replaced down the road.
