Vector quantity - Study guides, Class notes & Summaries

Vertical line on right side - Redline Airspeed, Velocity Never to Exceed As these vortices continue aft of wing, they continue as spiraling masses of air (Jet wash, Wake Turbulence) What three things happen as air becomes less dense for airplane: - Reduces power Reduces thrust Reduces lift Moment - Force applied at some distance from an axis or fulcrum F x d (Distance: from the point of rotation that is perpendicular to force, "moment arm") When are the four forces that act on an airp...

linear motion--free fall - when the ball is at the max height, the velocity v is 0. The max height the ball reaches above the ground is found by using: vf^2=vi^2+2ay projectile motion - obj has a velocity and position in both vertical and horizontal directions. no acceleration in the x direction, so particle moves with constant horizontal speed Force - Vector quantity. Units: N (kg*m/s^2) F=ma

rigid body - object of non-zero size that cannot change shape position - location and orientation CoG - average location of all weight of an object (typically in midline a bit below navel of humans) orientation in space - position with respect to the points of a compass or other directions motion of rigid body - change in position denoted by its location and orientation at every instant in time) distance - total distance travelled (SI unit: m) displacement - how far an object is from i...

AC HPAT Physics Exam Solved 100% Correct!! DIstance · Distance is a scalar quantity that refers to "how much ground an object has covered" during its motion. Displacement · Displacement is a vector quantity that refers to "how far out of place an object is"; it is the object's overall change in position. Position · Position is a place where someone or something is located or has been put. In physics, position is usually a number on an axis. ... Position is a vector, because...
