ASVAB Mechanical
Comprehension
Isaac Newton's laws of motion โ Ans - describe how the
acceleration of an object is related to its mass and the forces
acting on it.
Mechanical comprehension โ Ans - knowledge of
mechanics and physical principals; including concepts of force,
energy, work, and how they are used to predict the functioning
of tools and machines.
Review of Physics and Mechanical Principles โ Ans - The
proper use of tools and machinery depends on an
understanding of basic physics, which includes the study of
motion, and the interactions of mass, force, and energy.
International System of Units โ Ans - the system of units
(SI) used by scientists to measure the properties of matter
density โ Ans - the amount of mass that occupies a given
volume of space.
force โ Ans - the application of energy to an object with
the intent of changing its position.
acceleration โ Ans - the change in its velocity in a given
period of time. To understand it, it's necessary to relate to
displacement and velocity.
displacement โ Ans - the distance an object travels.
velocity โ Ans - the distance an object travels in a unit of
time, such as miles per hour or meters per second.
