During the early stages of the First World War‚ technology was progressing and it particularly obvious in aircraft. New forms of aviation were introduced such as zeppelins and aeroplanes. As the war came to an end‚ airships were replaced with the extensive use of zeppelins. The use of aeroplanes and zeppelins was a potent part in the attack and defence of the British main lands. Source A was produced as a poster in 1915 which was one year into the First World War. As a result‚ the source does not

Law of Inertia‚ an object in motion will continue in the same motion unless acted by an outside force. Aircraft in flight is an example of First Law of Motion‚ four forces on an aircraft; lift‚ weight‚ thrust‚ and a drag. Consider the motion of an aircraft at constant altitude‚ we can neglect the lift and weight‚ a cruising aircraft at constant speed and the thrust balances the drag of the aircraft. This is the first part sited in Newton’s First Law; there is no net force on the airplane and it travels

are unstable and known to have caused many deaths‚ so they are not used today. Square parachutes obtain a cross-shaped design preventing the parachute from swinging around. Skydivers are known to use these types of parachutes. Ram air parachutes are self-inflating‚ controlling direction and speed‚ making the ride down more flowey and less jerky. The sixth known parachute design is the Ribbon or Ring parachute; which is designed to control supersonic speeds that can lead to the canopy breaking. But

down. We made this modification because the wings of the airplane enable it to fly farther since it makes the airplane stay longer in the air. We believed that because the wings enlarge the volume of the airplane‚ the air resistance on it would become more‚ making it able to stay in the air longer. The wings also act as vertical stabilizers of the plane. Therefore‚ by bending down the tip of the plane‚ we believed that it would essentially act as a ‘third wing’‚ which would help our plane glide for an

major weather hazards that cause a number of aircraft accidents. It is a hazard that can snowball out of control and cause problems such as reduce aircraft efficiency by increasing weight‚ reduce lift‚ decrease thrust and increase drag. These effects can cause the aircraft to increase stalling speed or cause the aircraft to force downward in flight. Over the years‚ aircraft engines and airframes have changed dramatically. Modern day aircraft are aerodynamically less accepting of airfoil
