if any object is in aircraft so it will have velocity same as that of aircraft ,right ? and say in case it is thrown out of aircraft in between will it retain that velocity provided that no external force act on it?
elusiveshame said:If I understand right, the object has zero velocity in it's own reference frame, until it's dropped out of the plane, in which it would have the same velocity of the plane.
Much like a cup on a dashboard of a car; it's not moving from it's spot on the dashboard until you slam the brakes or have another external force acting upon it.

so ,when it is thrown out of aeroplane it would have same velocity as that of aeroplane,is this because of inertia?[/QUOTE]elusiveshame said:If I understand right, the object has zero velocity in it's own reference frame, until it's dropped out of the plane, in which it would have the same velocity of the plane.

when you throw something out of the aircraft, it implies directly that external force IS acting on it.gracy said:if any object is in aircraft so it will have velocity same as that of aircraft ,right ? and say in case it is thrown out of aircraft in between will it retain that velocity provided that no external force act on it?

Look at the picture and decide if it looks counter-intuitive or not! oo)
A.T. said:It becomes less counter-intuitive if you consider the velocity of the fighter relative to the bomber, which is not south, but south-west.
But the picture is also misleading, probably because it is not correctly scaled. What it shows would apply if the fighter was still further north (which probably was the normal situation when the gunner started firing).
In the situation shown in the picture however, the gunner should aim at the fighter if the planes have the same speeds, and in front of the fighter if the fighter is faster than the bomber (the likely case). So the picture is physically wrong, but it gives the right practical advice for the start of the fire. Real life was more complex anyway because the fighters were changing direction.
450 km/h is nearly the maximal speed for the bombers like B-17, B-26. Their cruise speeds where around 300km/h. I think that speed ratios of up to 2:1 are realistic.late347 said:Let's say that Fighter is moving at 650 km/h and bomber is moving at 450 km/h
Aircraft velocity refers to the speed at which an aircraft is moving through the air. It is typically measured in units of distance per time, such as miles per hour or kilometers per hour. It is an important factor in determining an aircraft's performance and fuel efficiency.
Aircraft velocity is calculated by dividing the distance traveled by the aircraft by the time it takes to travel that distance. This can be done using the formula: velocity = distance / time. It can also be calculated using instruments on the aircraft, such as an airspeed indicator.
Air density has a significant impact on aircraft velocity. As air density increases, the aircraft needs to travel faster to generate enough lift to stay in the air. This is why aircraft typically fly at higher speeds at higher altitudes where the air density is lower. Additionally, air density affects an aircraft's fuel efficiency, as denser air requires more fuel to maintain a certain velocity.
Airspeed refers to the velocity of an aircraft relative to the air surrounding it. It is measured by instruments on the aircraft. Ground speed, on the other hand, refers to the velocity of the aircraft relative to the ground below it. It takes into account factors such as wind speed and direction. Ground speed is typically higher than airspeed due to the effect of wind on the aircraft's movement.
Air resistance, also known as drag, is a force that acts in the opposite direction of an aircraft's motion through the air. As an aircraft's velocity increases, so does the amount of air resistance acting on it. This means that the aircraft needs to generate more thrust to maintain its velocity. At high velocities, air resistance can significantly impact an aircraft's performance and efficiency.
