ASVAB Mechanical Comprehension

ASVAB Mechanical Comprehension Isaac Newton's laws of motion ️Ans - describe how the acceleration of an object is related to its mass and the forces acting on it. Mechanical comprehension ️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 ️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 ️Ans - the system of units (SI) used by scientists to measure the properties of matter density ️Ans - the amount of mass that occupies a given volume of space. force ️Ans - the application of energy to an object with the intent of changing its position. acceleration ️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 ️Ans - the distance an object travels. velocity ️Ans - the distance an object travels in a unit of time, such as miles per hour or meters per second. magnitude ️Ans - The fact that velocity has a _________________ (speed) and a direction makes it a vector quantity. Isaac Newton's Second Law of Motion ️Ans - A force that acts on a body accelerates it in the direction of the force. The larger the force the
