📌 Newton’s Second Law

Q1. What does Newton’s Second Law state?
Ans: The acceleration of an object is directly proportional to the force applied and inversely proportional to its mass.

Q2. What is the formula for Newton’s Second Law?
Ans: F = m × a

Q3. What is the SI unit of force?
Ans: Newton (N)

Q4. If a force of 50 N is applied on a 10 kg body, what will be its acceleration?
Ans:
a = F ÷ m = 50 ÷ 10 = 5 m/s²

📌 Momentum

Q5. What is momentum?
Ans: Momentum is the quantity of motion in a moving object.

Q6. What is the formula for momentum?
Ans: p = m × v

Q7. What is the SI unit of momentum?
Ans: kg m/s

Q8. What is the Law of Conservation of Momentum?
Ans: The total momentum before and after a collision remains the same.

Q9. If a ball of 3 kg is moving at 5 m/s, what will be its momentum?
Ans: p = 3 × 5 = 15 kg m/s

📌 Impulse

Q10. What is impulse?
Ans: Impulse is the change in momentum in a very short time.

Q11. What is the formula for impulse?
Ans: Impulse = F × t = m(v-u)

Q12. What is the SI unit of impulse?
Ans: Newton-second (N·s)

Q13. If a force of 5 N acts for 3 seconds, what is the impulse?
Ans: Impulse = F × t = 5 × 3 = 15 N·s

Q14. If a ball’s mass is 4 kg, its initial speed is 2 m/s, and its final speed is 6 m/s, what is the impulse?
Ans:
Impulse = m(v-u) = 4 × (6-2) = 4 × 4 = 16 N·s
