ACollisions between two moving objects
BMotion produced by unbalanced forces
CEnergy stored inside stretched springs
DForces acting on systems in equilibrium
Answer & Solution
Correct answer: D. Forces acting on systems in equilibrium
1. Statics is the study of forces in equilibrium, a special case of Newton's second law.
2. Equilibrium here means the system has neither linear nor rotational acceleration.
3. Motion produced by unbalanced forces is dynamics, the opposite starting point.
4. Stored elastic energy and collisions belong to other branches of mechanics.
