Newton’s Laws of Motion

Newton’s laws of motion are the cornerstone of classical mechanics. They describe the relationship between an object’s motion and the forces acting upon it.

  • Newton’s First Law (Law of Inertia):An object at rest stays at rest, and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
  • Newton’s Second Law (Law of Acceleration):The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.
  • Newton’s Third Law (Law of Action-Reaction):For every action, there is an equal and opposite reaction.

Mastering the concepts of Unit 2 is crucial, and practicing with sample MCQ questions is an effective way to gauge your understanding. Let’s delve into a variety of questions that cover the unit’s key concepts, complete with answer choices and detailed explanations.

Kinematic Equations

  • A car accelerates uniformly from rest at a rate of 2 m/s 2for 10 seconds. What is its final velocity?
    • A. 10 m/s
    • B. 20 m/s
    • C. 30 m/s
    • D. 40 m/s

    Answer: B. 20 m/s

    Explanation:Using the equation v = u + at, where u is the initial velocity (0 m/s), a is the acceleration (2 m/s 2), and t is the time (10 seconds), we get v = 0 + 2 – 10 = 20 m/s.

Dynamics

  • A block of mass 5 kg is pushed with a force of 10 N. What is its acceleration?
    • A. 0.5 m/s 2
    • B. 1 m/s 2
    • C. 2 m/s 2
    • D. 5 m/s 2

    Answer: B. 1 m/s2

    Explanation:According to Newton’s second law, F = ma, where F is the force (10 N), m is the mass (5 kg), and a is the acceleration. Solving for a, we get a = F/m = 10 N / 5 kg = 1 m/s 2.

Circular Motion

  • A car travels around a circular track of radius 50 m at a constant speed of 10 m/s. What is its centripetal acceleration?
    • A. 0.2 m/s 2
    • B. 1 m/s 2
    • C. 2 m/s 2
    • D. 5 m/s 2

    Answer: A. 0.2 m/s2

    Explanation:Centripetal acceleration is given by a = v 2/r, where v is the speed (10 m/s) and r is the radius (50 m). Plugging in the values, we get a = (10 m/s) 2/ 50 m = 0.2 m/s 2.
