Question
In which of the following situations is the force that moves the rock acting from a distance? A. A hammer hits the rock. B. A rock falls through the air. C. A bulldozer pushes the rock. D. A person kicks the rock.
Solution
The force that moves the rock acting from a distance is in situation B. A rock falls through the air. This is due to the force of gravity, which acts at a distance. In the other situations (A, C, and D), the forces are contact forces, meaning they require direct physical contact to move the rock.
