WebA. If an object is at rest, then there are no forces at all acting on the object. B. An object can have a nonzero velocity even when the net external force on it is zero. C. A force is always required to sustain motion at constant velocity. D. A rock thrown straight up has zero net force at the top of its trajectory. E. WebBy Newton's second law of motion, if there is a nonzero net force there is an acceleration. If there is no acceleration then the net force is zero. In the situation you describe, where the box has no acceleration, there must be another force balancing F a p p otherwise there will be an acceleration. Share Cite Improve this answer
Zero Net Force Quick Check Flashcards Quizlet
Web28 okt. 2024 · A) If the net force acting on an object is zero, it does not accelerate. B) When one object exerts a force on a second object, the first object exerts an equal force on itself in the opposite direction. C) Acceleration of an object is proportional to net force divided by mass. D) When you push on an object, it pushes back just as strongly on you. WebIf the net force acting on an object is zero, the object remains at rest, and if the object is already moving, continues to move in a straight line with constant speed. Weight The gravitational force between you and the Earth. Center of Mass The point in which an … irb in nursing research
newtonian mechanics - Acceleration is zero, for non-zero net force ...
WebThe zero force related to zero acceleration is not a property of the object, it is a statement about the forces acting on the body.That is your title should not read "has no force" but "is subject to no net force".. If a body has a non-zero, but constant, velocity then we know that the total of all the forces applied to it is zero (from Newton's Laws). Web10 feb. 2016 · Explanation: A force, F, applied to an object causes an acceleration, a, which we know from Newton's 2nd law: F = m ⋅ a or a = F m Acceleration is the change of velocity per unit time, so if there is no force, all we know is that the acceleration is zero. Therefore, the velocity is not changing. WebA. The net torque acting on the object must equal zero B. Friction cannot exert a torque on the object C. The net torque on the object does not have to be zero if the net force on the object is zero D. The net force on the object does not have to be zero if the net torque on the object is zero Expert Answer 100% (13 ratings) order and frequency
