First, a constant force will NOT cause an object to accelerate faster and faster; it will cause a constant (non-changing) acceleration. Only a changing force can cause a changing acceleration. That being said, a constant force can cause an object to move faster and faster--in which case the displacement is changing non-linearly, the velocity is changing linearly, and the acceleration is not changing at all (i.e., it is constant). A related misconception is that a constant force applied to an...

True or false: 1) If a net force acts on an object, the object's speed will change. 2) The net force which acts on an object which remains at rest is zero. 3) An object's velocity will change if a net force acts on the object. 4) If a net force acts on an object, the object's velocity will change. 5) If an object's speed does not change, no net force is acting on the object. Please write why they...

14. At a certain instant, a partide-like object is acted on by a force F=8.0i+4.0j-2.0k (in N) while the object has a velocity given by V=4.0i-2.0k (in m/s). What is the instantaneous power at which this force does work on the object. A.28W B.40W C.36W D.32W E.24W

A descending parachutist is acted on by two forces: a constant downward force mg and the upward force of air resistance, which (within close approximation) is of the form −βv2 where β is a positive constant. (In this problem we are taking the downward direction as positive.) (a) Express t in terms of the velocity v, the initial velocity v0, and the constant vc =√mg/β. (b) Express v as a function of t. (c) Express the acceleration a, as a...
