By practicing with these questions students will get acquainted with the key concepts which must be prepared to score high marks in the objective type questions in the Class 9 Science Annual Exam 2020. Answer: According to second law, F = ma If F = 0, a =0 since m ≠ 0, But a = $$\frac{v-u}{t}$$ or, v – u =0 so, v = u for whatever time t is taken. Examples: Examples: (i) When a moving car suddenly stops the person sitting in the car falls forward because the lower portion of the body in contact with the car comes to rest whereas the upper part tends to remain in motion due to inertia of motion.
