... Objects that move in any fluid have a drag force acting on them. This drag force is a function of velocity. If the ship has an initial velocity vo and the magnitude of the opposing drag force at any instant is half the velocity, how long it would take for the ship to come to a stop if its engines st ...

Forces and The Laws of Motion
... • When the net external force on an object is zero, its acceleration is zero • Conversely, an object that is not accelerating has no net force acting on it • Net force is vector sum of all forces: • Bodies at rest will stay at rest and bodies in motion will stay in straight-line motion at a constant ...

... The force that two surfaces exert on each other when they rub against each other. ◦ Acts in the direction opposite to the objects motion. Friction opposes motion. ◦ Eventually friction will cause an object to come to a stop. ◦ Without friction the object would continue to move at a constant speed un ...
