Lung Capacity01:47

Lung Capacity

44.4K
The air in the lungs is measured in volumes and capacities. Lung volume measures reflect the amount of air taken in, released, or left over after a lung function, like a single inhalation. Lung capacity measures are sums of two or more lung volume measures.

Weightlessness01:01

Weightlessness

5.4K
When an object is dropped, it accelerates toward the center of the Earth. If the net external force on the object is its weight, it is said to be in free fall; that is, the only force acting on the object is gravity. Galileo was instrumental in showing that, in the absence of air resistance, all objects fall with the same acceleration g. However, when objects on the Earth fall downward, they are never truly in free fall, because there is always some upward resistance force from the air acting...

Rocket Propulsion in Empty Space - I

2.7K
The driving force for the motion of any vehicle is friction, but in the case of rocket propulsion in space, the friction force is not present. The motion of a rocket changes its velocity (and hence its momentum) by ejecting burned fuel gases, thus causing it to accelerate in the direction opposite to the velocity of the ejected fuel. In this situation, the mass and velocity of the rocket constantly change along with the total mass of ejected gases. Due to conservation of momentum, the...

Rocket Propulsion in Gravitational Field - II01:03

Rocket Propulsion in Gravitational Field - II

2.0K
A rocket's velocity in the presence of a gravitational field is decreased by the amount of force exerted by Earth's gravitational field, which opposes the motion of the rocket. If we consider thrust, that is, the force exerted on a rocket by the exhaust gases, then a rocket's thrust is greater in outer space than in the atmosphere or on a launch pad. In fact, gases are easier to expel in a vacuum.
A rocket's acceleration depends on three major factors, consistent with the...

Drag Force and Terminal Speed01:18

Drag Force and Terminal Speed

3.3K
An interesting force in everyday life is the force of drag on an object when it is moving in a fluid. Like friction, the drag force always opposes the motion of an object. Unlike simple friction, the drag force is proportional to some function of the velocity of the object in that fluid. This functionality is complicated and depends upon the shape of the object, its size, its velocity, and the fluid it is in. For most large objects, such as cyclists, cars, and baseballs, that are not moving too...

Problem Solving: Volume01:13

Problem Solving: Volume

230
The volume of a fuel tank mounted on the wing of a jet aircraft can be modeled using the concept of solids of revolution. In this case, the tank is formed by rotating a two-dimensional region, defined by a mathematical function, about the x-axis. The region extends along the axis from zero to two meters, and the resulting three-dimensional shape is symmetric about the axis of rotation. Because the boundary curve lies directly against the axis, the disk method is an appropriate technique for...

Area of Science:

  • Human Factors
  • Cognitive Psychology
  • Military Aviation Psychology

Background:

  • Spatial ability is critical for military aviator selection.
  • The Direction Orientation Task (DOT) is the sole spatial ability measure for US Navy aviation applicants.
  • Concerns exist regarding the DOT's psychometric properties and potential ceiling effects.

Purpose of the Study:

  • To evaluate the current construct and incremental validity of the DOT.
  • To investigate changes in DOT performance over time.
  • To examine the relationship between DOT performance and strategy use.

Main Methods:

  • Analysis of historical Naval Aviator applicant data (six years).
  • Empirical study of DOT performance and strategy in student aviators and air traffic controllers.
  • Comparison of analytic versus spatial strategy use in relation to DOT scores.

Main Results:

  • 22% of applicants achieved 90%+ accuracy on the DOT.
  • Significant performance increases observed over time, indicating potential ceiling effects.
  • Analytic strategy use correlated with higher DOT performance; spatial strategy did not.

Conclusions:

  • The DOT's validity as a measure of spatial ability may be diminishing.
  • Increased performance and strategy use suggest the DOT may lack construct and incremental validity.
  • The findings necessitate a re-evaluation of the DOT for military aviation selection.
