Which one of the following force is non-conservative:
Correct answer: A. Frictional force
- A. Frictional force
- B. Gravitational force
- C. Electric force
- D. Elastic spring force
Explanation
Frictional force is non conservative fields while elastic string force, electric, magnetic, and gravitational fields are constants. Non-conservational simply means energy is lost to the surroundings and does not get recycled.

About Force and Motion
Displacement, velocity and acceleration describe motion, including the horizontal and vertical components of projectile motion. The chapter connects these quantities with Newton's laws, momentum and impulse, then applies conservation of momentum to collisions, distinguishing elastic collisions from inelastic ones.
