Chinese sailors attached to kites - Answer - What could be considered the first "manned aircraft"? Montgolfier brothers - Answer - Who created the first manned hot air balloon? Newton's First Law of Motion - Answer - An object at rest will remain at rest unless acted upon by an unbalanced, outside force Newton's Second Law of Motion - Answer - A force acting upon a body causes it to accelerate in direction of the force. Acceleration is directly proportional to the force and inversely proportional to the mass of the body being accelerated. Newton's Third Law of Motion - Answer - For every action there is an equal and opposite reaction. Yoke - Answer - another name for the control stick Lateral Axis - Answer - controls pitch Lift, gravity, thrust, drag - Answer - What are the four forces of an airplane? gravity, drag - Answer - The two natural forces thrust, lift - Answer - The artificial forces Vertical Axis - Answer - controls yaw Longitudinal Axis - Answer - controls roll Roll - Answer - rotation on the longitudinal axis Yaw - Answer - rotation on the vertical axis Pitch - Answer - rotation on the lateral axis UAV - Answer - Unmanned Aerial Vehicle altitude - Answer - the height or distance above a reference plane convection - Answer - fluid motion between regions of unequal heating density - Answer - mass in a given volume glide ratio - Answer - a mathematical relationship between the distance an aircraft will glide forward to the altitude loss lapse rate - Answer - the average rate at which temperature decreases with an increase in altitude
