A car travels 200 Km/h and there's a fly inside the car. Does the fly travels with the same speed as the car?

Question

Let's suppose the fly is flying and not in contact with any part of the car.

Answer 1

Everything in the car is going the same speed as the car, if the fly is going towards the rear of the car it's going slower than the travel of the car, if it's going towards the front it's going faster than the car, the HUGE difference is, inside the car, all objects are not acted upon by the friction of the wind created by forward motion of the car.

Answer 2

The fly is in contact with the air in the car, which is travelling together with the car. Speed is a relative thing. The fly has speed 0 in relation to the car, but speed 200 km/h in relation to the road. If another car comes the other direction with a speed of 200 km/h, the fly travels at 400 km/h in relation to that car.

Answer 3

If the car was accelerating with the fly inside, the fly would be thrown to the back of the car. If the car was traveling at a constant speed, it is hard to say without more information.

Answer 4

The car is moving with a speed of 200 km/h.
if the car is closed, then air, the fly and the passenger every thing in the car is moving with a speed of 200 km/h.

This speed is with respect to an observer on the road.

Now if the fy is flying with a speed of 2 km/h in the direction of motion of car, this speed is with respect to the car.

For the observer on the road, the fly is flying with a speed of

200 + 2 = 202 km / h in the direction of the car.

This speed is more than the car.

If the fly is flying toward the back of the car; this is speed with respect to the car.

For the observer from the road the speed of the fly is 200 - 2 = 198 km/h. toward the direction of the car.

This speed is less than the car; but it is in the direction of the car; wheras for the obsever in the car it seems to fly backward direction.

Answer 5

Hi ricardo..

This is a good question. The answer would depend on how u understand what is known as INERTIA. Inertia is nothing but the force experienced by an object by virtue of its state of either rest or motion. In classical physics by Newton's first Law of motion "Every body perseveres in its state of being at rest or of moving uniformly straight ahead, except insofar as it is compelled to change its state by forces impressed."

Consider this example, presume you are traveling by train. U happen to throw a ball up in the air, the ball invariably comes down straight though the train has been moving forward. This is bcoz the ball is in inertia of motion with respect to the train.

Similarly when u someone jumps off a running bus they fall down because they are suddenly brought to inertia of rest from inertia of motion.

Hence a fly inside a car even if it is not in contact with the car was actually in inertia of motion having an inertia corresponding to that of the speed of the car. So the fly is having an inertial force and if it flies at say 2 kmph with the car at 200 kmph, the fly would still be flying at 2 kmph+inertial force of the car. Hence practically it is flying only at 2 kmph and not 202 kmph.

Hope this clears it. otherwise try askin ur faculty.

Answer 6

In a vacuum NO, but with air YES. When the car starts, the fly may get pushed back a little, but the air inside the car will drag him along. To a fly, air is like a swimming pool.

Answer 7

He only travels the same speed of the car if he flys in place in respect to the rest of the car. Otherwise the fly will either be going faster or slower...depending on the direction and speed of his flight.

Answer 8

If the fly is sitting on any part of the car, it is travelling at the velocity equal to that of the car. But its velocity can even be higher or lower than that of the car. It depends on the direction in which it is flying. Infact , anything inside the car is moving at lease equal to the velocity of the car.

Answer 9

Velocity is relative, of course, so you have to define your terms a little more--you have to define your frame of reference.

Example 1: Relative to a passenger inside the car, the fly is moving quite slowly, maybe 2 km/h.

Example 2: Relative to a person standing on the side of the road, however, the fly is moving at 202 km/h.

Answer 10

yes the fly is going with same speed as the car
