# Would a fly collide with the back of a car if it moves from the dashboard at 100km/hr

Assuming a car is travelling at 100km/hr and there is a fly on the dashboard of the car, if the housefly attempts to fly , would it collide with the back glass of the car or it would move with the same velocity as the car thus being stationary.

Assuming the same situation in a plane traveling at 800km/hr ie 222m/s , would the fly collide with part of the plane .

When you fly on a plane, and you jump do you splat against the rear of the plane? Why do you think this is?

What do you think? This sounds a lot like schoolwork, and you are required to show some effort in solving schoolwork questions. What do you think will happen, and why?

I actually tried that on a train when I was about five or six years old. I think I was a bit nervous before I jumped.

Yet you lived to tell the tale. Perhaps that indicates something to the OP

I used to ask myself this, then I read Newtons First Law :)

I've never asked myself this since I've been in a vehicle with a fly a number of times trying to get the pesky critters out the window.
