The bomb after being dropped from the plane will have only horizontal velocity but zero vertical velocity. This scenario is as same as if a body is horizontally projected from a top of tower and it hits the ground tracing a parabolic path. Hence the trajectory of the bomb is also a parabola.

What are the forces acting on a falling bomb?
The two primary forces during its fall are gravity and air drag, which make the path of the bomb through the air roughly parabolic.
Why bomber does not drop the bomb when it is vertically above the target?
In order to drop the bomb on the target just below the bomber plane, The bomber plane must be in the rest condition which is not possible and when the bomber plane is in the moving condition then it will add a velocity component to the bomb due to which the bomb will follow a trajectory and will miss the target.
How long will it take for the bomb to hit the ground after it is dropped from the plane?
Since, the vertical initial velocity of the bomb is zero, $u=0$; it is moving with a constant acceleration, $a=g=9.8,m/s$. The distance, bomb has to travel is $s=h=980m$. The bomb will take 14.14 seconds to hit the ground.
How do planes drop bombs?
How fast do bombs drop?
With 1000-lb bombs, having good stream lines, we can expect a terminal velocity of about 1,100 feet per second, but to attain such velocity they would have to be dropped from an altitude of about thirty or forty thousand feet.
What physical quantity remains constant in a bomb explosion?
Mass of the bomb remains unchanged. This scenario includes mass being converted to energy. Momentum is not conserved in this situation because an external force, gravity, is acting on your system, the bomb.
How does a ww2 bomb sight work?
In operation, the sight would be set far in advance of the aim point, and as the bomber approached the target the sighting point indicator would slowly slide toward the aim point. When the two met, the bombs were automatically released.
What does bombsight mean?
bombsight. / (หbษmหsaษชt) / noun. a mechanical or electronic device in an aircraft for aiming bombs.
How did people survive Hiroshima?
Shockingly, survival close to ground zero is possible. When Hiroshima and Nagasaki were dropped, some people were sheltered by the sturdy walls of banks or basements. The reports of those who did survive paint a very dark picture.
Why did the US drop a bomb on Hiroshima?
In order to avoid such a high casualty rate, Truman decidedโover the moral reservations of Secretary of War Henry Stimson, General Dwight Eisenhower and a number of the Manhattan Project scientistsโto use the atomic bomb in the hopes of bringing the war to a quick end.
How did Japan react to Hiroshima?
Around this time, the Army Air Forces began showering Japan with propaganda leaflets explaining what the bombers were and what they had done. They were made to look like little Japanese newspapers, with pictures of the mushroom cloud over Hiroshima. And on the next day, Hirohito announced the surrender.
Who invented the first bomber?
2 aircraft piloted by Radul Milkov, during the First Balkan War. This is deemed to be the first use of an aircraft as a bomber. The first heavier-than-air aircraft purposely designed for bombing were the Italian Caproni Ca 30 and British Bristol T.B. 8, both of 1913.
Who invented air bombing?
Captain Simeon Petrov developed the idea and created several prototypes by adapting different types of grenades and increasing their payload. On 16 October 1912, observer Prodan Tarakchiev dropped two of those bombs on the Turkish railway station of Karaฤaรง (near the besieged Edirne) from an Albatros F.
Do bombs whistle when dropped?
The Sound of Falling Bombs Typically, a metal object with sharp edges, like a bomb would make a small noise “hissing” sound as it fell through the air, unless it happened to exceed the sound barrier (343 meters per second), which would result in a sonic boom.
What are bombs made of?
The outer case is most commonly made of metal and has a point at its tip, or nose. The explosive charge in most conventional bombs usually consists of TNT, RDX, ammonium nitrate, or other high explosives in combination with each other.
How big is a 500 pound bomb?
MK-82 500 lb, Free Fall, General Purpose Bomb. Dimensions: Length 7 ft. 6.2 in., diameter 18 in.. Image created by Virginia Reyes of the Air Force News Agency.
What is a 500 pound bomb?
The Mk 82 aircraft bomb and its guided variants have been used extensively throughout the world and are one of the most common families of air-delivered munitions ever produced. The Mk 82 and its variants are 500-pound (227 kg) class, low-drag, general-purpose aircraft bombs containing 89 kg of high explosive.
What is a 3 ton bomb?
The FAB-3000 is an unguided 3,000 kilograms (6,600 pounds) bomb, which was primarily designed for the destruction of industrial, urban, and port facilities. This type of bomb was used by both Soviet bombers, the Tupolev Tu-16 and the Tupolev Tu-22M, during the war in Afghanistan in the 1980s.
How big of a bomb can we make?
We could make something at least 100 times more powerful. Tsar Bomba was the largest nuclear bomb ever, yielding an explosion equivalent to 57 megatons of TNT, ten times more powerful than all of the combined munitions used during World War II.
What is an explosion physics?
When an object explodes, it breaks up into more than one piece and it therefore changes its shape. Explosions occur when energy is transformed from one kind e.g. chemical potential energy to another e.g. heat energy or kinetic energy extremely quickly.
When was the bomb sight invented?
In 1927, after six years of work, they produced their first successful bombsight. The Navy had returned an earlier prototype created by the team for modification, but the second versionโa marvel of designโwas quickly approved.
Why was the Norden bombsight so good?
“What did the Norden Bombsight do? It allowed you to bomb only those things which you absolutely needed and wanted to bomb.” The Norden, essentially an analog calculator, could adjust for air density, wind drift, the bombers airspeed and groundspeed while controlling the bombers’ final run on the target.
What bomb sight did the RAF use in ww2?
The Mark XIV Bomb Sight was a bombsight developed by Royal Air Force (RAF) Bomber Command during the Second World War. It was also known as the Blackett sight after its primary inventor, P. M. S. Blackett.
Who invented the bomb site?
The Norden bombsight was crucial to the success of the U.S. Army Air Forces’ daylight bombing campaign during World War II. Initially developed by Carl Norden for the U.S. Navy, the Army Air Corps acquired its first Norden bombsight in 1932.
