A heavy mirror hangs from a string and is at rest because the tension in the string that pulls

the mirror upward is equal and opposite to the force of gravity that pulls the mirror downward.

The tension in the string and the force of gravity on the mirror are an action-reaction pair as

described in Newton's Third Law of Motion. Explain why this statement is true or false.

1. A box is at rest on a flat table. Which of the following is true? a. The normal force and the gravitational force are equal in magnitude and opposite in direction. b. The magnitude of normal force depends on the coefficient of static friction between the book and the table. c. Gravity exerts a force on the box that depends on how big the normal or support force is. d. The normal force and the gravitational force are an...

1. For a stationary ball of mass m = 0.200 kg hanging from a massless string, draw arrows (click on the “Shapes” tab) showing the forces acting on the ball (lengths can be arbitrary, but get the relative lengths of each force roughly correct). For this case of zero acceleration, use Newton’s 2nd law to find the magnitude of the tension force in the string, in units of Newtons. Since we will be considering motion in the horizontal xy plane,...
