Anyone interested in joining the military is required to take the Armed Services Vocational Aptitude Battery (ASVAB) exam. The Armed Services Vocational Aptitude Battery (ASVAB) is also used for those who are not wishing to enter the military to help determine what type of career is best fit for them. The ASVAB also helps to identify the individual’s strengths and weaknesses as well as their interests.
Individuals taking the ASVAB exam will be tested based on their knowledge of:
• general science
• arithmetic reasoning
• word knowledge
• paragraph comprehension
• mathematics knowledge
• electronics information
• auto and shop information
• assembling objects
• mechanical comprehension
ASVAB Mechanical Comprehension Prep
The Mechanical Comprehension section of the ASVAB exam tests your ability to understand mechanical concepts. You will be given a picture and a question with three possible answers. Be sure that you read the question carefully, study the picture, and decide which answer is correct.
A cannon fires off a ship up towards a mountain range. Neglecting air resistance, where will the velocity of the projectile be greatest?
a. Exiting the muzzle
b. Halfway to the mountains
c. As it impacts the mountains
A, The velocity is made up of two components, the x and y components. The x component is not changing during flight, but the weight of the projectile decreases the positive y component of the velocity. Thus, the total velocity will be greatest before the y component has decreased.
