FAQs on Laws of Motion JEE Main 2025-26 Mock Test: Practice & Solutions
1. What are Newton's laws of motion?
Newton's laws of motion are three fundamental principles describing the relationship between the motion of an object and the forces acting on it:
1. First Law (Law of Inertia): An object remains at rest or in uniform motion in a straight line unless acted upon by an external force.
2. Second Law: The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass (F = ma).
3. Third Law: For every action, there is an equal and opposite reaction.
2. State Newton's First Law of Motion with an example.
Newton's First Law of Motion states that an object will remain at rest or move with uniform velocity unless acted upon by a net external force. For example, a stationary football remains at rest on the ground until a player kicks it (an external force), causing it to move.
3. How do force and mass affect acceleration according to Newton's Second Law?
Newton's Second Law establishes that the acceleration of an object depends on both the net force applied and its mass. As per the formula (F = ma), increasing the force increases acceleration, while increasing mass decreases acceleration if the force is constant.
4. What is inertia?
Inertia is the natural tendency of an object to resist any change in its state of rest or uniform motion. Greater mass means greater inertia. It is the basis of Newton's First Law of Motion.
5. Explain Newton's Third Law of Motion with a real-life example.
According to Newton's Third Law, every action has an equal and opposite reaction. For example, when you jump off a boat, you push the boat backwards as you move forward. The force your feet exert on the boat equals the force the boat exerts on you, but in opposite directions.
6. What is the difference between balanced and unbalanced forces?
Balanced forces are equal in magnitude and opposite in direction, causing no change in an object's motion. Unbalanced forces are not equal and result in a change in the object's velocity or direction, producing acceleration.
7. How is a force measured, and what is its SI unit?
Force is measured using a spring balance or similar device. The SI unit of force is the Newton (N), defined as the force needed to accelerate a 1 kg mass by 1 m/s2.
8. What is meant by momentum? State the law of conservation of momentum.
Momentum is the product of an object's mass and velocity (p = mv). The law of conservation of momentum states that total momentum of an isolated system remains constant if no external forces act on it.
9. Can you give an example of the law of conservation of momentum?
A classic illustration is two ice skaters pushing each other apart. Both move in opposite directions, but the total momentum before and after the push remains the same, provided no external force acts.
10. Why do passengers lurch forward when a moving bus suddenly stops?
Passengers lurch forward due to inertia. Their bodies tend to remain in motion when the bus stops suddenly, so they move forward relative to the stopping bus.
11. What does a force-time graph for an impulsive force look like?
An impulsive force acts over a very short time, appearing as a sharp spike or narrow peak on a force-time graph. The area under the curve represents impulse (change in momentum).
12. How can Newton's laws of motion be applied to solve JEE-level problems?
To solve JEE-level problems on laws of motion, carefully identify forces acting, apply Newton's Laws (especially F = ma), draw clear free-body diagrams, and use the law of conservation of momentum where relevant. Practice simulations and mock tests help reinforce these concepts for competitive exams.
