1. What will the buoyancy of an object be (positive, neutral, or negative) if it displaces an amount of water Answer a. more than its own weight? b. less than its own weight? c. equal to its own weight? Answer a. positive Answer b. negative Answer c. neutral 2. How does the buoyancy of an object differ in fresh water compared to salt water. Answer Because salt water weighs more than fresh water, it causes more buoyancy (more upward force) 3. What is the relationship between incr...

Mechanical ASVAB Latest Update (Scored A) force Changes the velocity of an object friction Acts in opposition to motion, causes effort work to be larger than load work equilibrium Net force is zero when velocity is not changing viscous drag Like friction, however increases with speed, varies by shape gravity Causes objects to fall mass Amount of substance weight Force of gravity on a mass lift Caused by higher speed air flow over a lower speed air flow camber When a surface is curved ai...
