Resistive forces are;
Correct answer: A. Nonconservative
- A. Nonconservative
- B. Conservative
- C. Both conservative and nonconservative
- D. None of the above
Explanation
Non-conservative forces are those that do work on an object, resulting in dissipation or loss of energy. Resistive forces, such as friction, air resistance, and drag, are examples of non-conservative forces. These forces act opposite to the direction of motion, reducing the kinetic energy of an object.

About Work
Work is done when a force produces displacement, with its value determined by the component of force along the displacement. The topic covers positive, negative and zero work, work by variable forces from force-displacement graphs, and the connection between net work and change in kinetic energy.
