Question

daryl ties a rope to a brick and lifts the brick straight up. the free - body diagram below shows the brick when it is suspended above the ground. what is force 2 in this diagram? a. normal force b. weight c. tension d. friction

Explanation:

• Normal force acts perpendicular to a surface. Here, the brick is suspended, so no surface - related normal force.
• Weight is the force due to gravity acting vertically downward. In the free - body diagram of a suspended brick, the downward force is its weight.
• Tension is the force in the rope (upward force in this case, which would be Force 1).
• Friction opposes relative motion. There is no indication of motion or tendency of motion for friction to act.

Answer:

B. Weight
