What is the net force acting on a body moving with a constant velocity in a straight line?
A. Equal to its weight
B. Zero✓ Correct Answer
C. Infinite
D. Equal to mass times acceleration
💡 Solution & Explanation
According to Newton's first law of motion, an object moving with a constant velocity in a straight line experiences zero acceleration, which implies that the net external force acting on it is zero. Distractors incorrectly equate uniform motion with gravitational weight or nonzero acceleration forces. Dynamic equilibrium requires forces acting in opposing directions to completely balance out.
