B. more force is required to stop softer objects than to stop harder objects. C. objects in motion tend to stay in motion unless acted upon by an outside force. D. only objects touching the Earth's surface can be acted upon by an outside force.

An object's motion changes A. only if the object is at rest when a force acts upon it. B. only when a nonzero net force is applied to the object. C. when there are no forces acting upon it. D. when the forces acting on the object remain balanced.

7Which of the following statements is true about an object? A. If the object is moving, it will keep moving until acted on by a force. B. If the object is moving in a straight line, eventually it will change direction on its own. C. If the object is not moving, eventually it will start moving on its own. D. If the object is moving, eventually it will stop moving on its own.

Which of the following could not be caused by a resultant force acting on an object?The object speeds upThe object maintains constant velocityThe object slows downThe object changes direction

Which force always opposes the motion of an object?a) Gravitational forceb) Frictional forcec) Magnetic forced) Tension force

A book is resting on a horizontal table. When you push the book horizontally and let go, you observe that the book moves for a while and then stops. Which of the following statements is correct?Group of answer choicesthe book stops because a non-zero net force was working on it before stoppingthe book stops because it is the inherent property of all objects to come to restthe book stops because it does not want to fall from the tablethe book stops because the normal force on the book is equal to its weightthe book stops because the earth is pulling it down
