Thalia is drafting a plan to move a large, perfect sphere concrete sculpture that is in front of her office building. Describe the considerations Thalia would need to make if she was drafting a plan to move the sculpture.

Answer:

Thalia must consider Newton's three laws of motion. First, the sculpture has inertia, so a significant unbalanced force is needed to overcome its tendency to remain at rest (First Law). Second, the amount of force required depends on the sculpture's mass and the desired acceleration, calculated using F=ma (Second Law). Third, whatever force she applies to the sculpture, the sculpture will exert an equal and opposite force back on the mover or moving equipment (Third Law).
