The following statements are TRUE about Newton's Second Law of Motion EXCEPT:   Mass and acceleration is inversely proportional to each other given that force is constant.   If the net force on an object is not zero, it causes the object to accelerate.   Force and acceleration is inversely proportional to each other given that mass is constant.   Force and mass is directly proportional to each other given that acceleration is constant

A freight train consists of an engine and several identical cars on a straight, level track. Which of the following statements are true? A. If the train is moving at constant speed, the engine must be pulling with a force greater than the train's weight. B. If the train is moving at constant speed, the engine's pull on the first car must exceed that car's backward pull on the engine. C. If the train is moving at constant speed, the engine's pull must be equal to the force of friction. D. If the train is coasting, its inertia makes it slow down and eventually stop

1. Newton's 2nd Law stipulates that "the sum of all forces acting on an object are equal to the mass times the acceleration of that object." Given the force diagram below, calculate the acceleration of the object (both magnitude and direction). The object is the smiley face, which has a mass of 12.6 kg (it's a very heavy smiley face). FPush = 36.2 N %3D Fg = Weight

Which of the following statements is not one of Newton’s Laws on motion? a. In the absence of an unbalanced force, an object moves at constant velocityb. For any force there is always an equal but opposite reaction force.c. The force and the acceleration of a body are towards the same direction.
