Importance of Laws of Motion for NEET<\/h3>\n\n\n\n

Before diving into the Top 5 Laws of Motion Questions<\/strong>, it is essential to understand why this chapter is crucial. Laws of Motion act as the backbone of mechanics. Most NEET aspirants lose marks here not because the questions are difficult, but because they lack clarity in concepts like free body diagrams, friction, and force analysis.<\/p>\n\n\n\n

Practicing the Top 5 Laws of Motion Questions<\/strong> repeatedly ensures that you build both speed and accuracy, which are key for scoring high in NEET Physics.<\/p>\n\n\n\n

Top 5 Laws of Motion Questions (With Detailed Concepts)<\/h2>\n\n\n\n

Question 1: Block on a Rough Surface<\/h3>\n\n\n\n

A block of mass 5 kg is placed on a rough horizontal surface. A force of 20 N is applied, but the block does not move. The coefficient of static friction is 0.5. Find the frictional force acting on the block.<\/p>\n\n\n\n

This is a classic example included in the Top 5 Laws of Motion Questions<\/strong> to test your understanding of static friction. Many students directly calculate friction as \u03bcN, which is incorrect unless the body is about to move.<\/p>\n\n\n\n

Maximum static friction = \u03bcN = 0.5 \u00d7 (5 \u00d7 10) = 25 N. However, the applied force is only 20 N. Since static friction is a self-adjusting force, it matches the applied force as long as it is below the limiting value.<\/p>\n\n\n\n

Therefore, the frictional force acting on the block is 20 N. This question highlights the importance of conceptual clarity in the Top 5 Laws of Motion Questions<\/strong>.<\/p>\n\n\n\n

\n\n\n\n

Question 2: Two Blocks System<\/h3>\n\n\n\n

Two blocks of masses 2 kg and 3 kg are connected by a string and pulled with a force of 10 N on a frictionless surface. Find the acceleration of the system.<\/p>\n\n\n\n

This is one of the most frequently asked patterns in the Top 5 Laws of Motion Questions<\/strong>. Here, both blocks move together as a single system.<\/p>\n\n\n\n

Total mass = 2 + 3 = 5 kg. Using Newton\u2019s Second Law, acceleration = F \/ m = 10 \/ 5 = 2 m\/s\u00b2. The simplicity of this problem makes it scoring, provided you correctly treat the system as one unit.<\/p>\n\n\n\n

\n\n\n\n

Question 3: Tension in the String<\/h3>\n\n\n\n

Using the same system as above, find the tension in the string between the blocks.<\/p>\n\n\n\n

This is a follow-up question often paired with system problems in the Top 5 Laws of Motion Questions<\/strong>. To find tension, isolate one block (say 2 kg).<\/p>\n\n\n\n

Using F = ma, T = 2 \u00d7 2 = 4 N. This question emphasizes internal force analysis and is extremely important for NEET.<\/p>\n\n\n\n

\n\n\n\n

Question 4: Elevator Problem<\/h3>\n\n\n\n

A person of mass 60 kg is standing in an elevator accelerating upward with 2 m\/s\u00b2. Find the apparent weight.<\/p>\n\n\n\n

Elevator problems are a staple in the Top 5 Laws of Motion Questions<\/strong>. These test your understanding of non-inertial frames.<\/p>\n\n\n\n

Apparent weight = m(g + a) = 60 \u00d7 (10 + 2) = 720 N. The key idea here is that upward acceleration increases normal reaction, hence increasing apparent weight.<\/p>\n\n\n\n

\n\n\n\n

Question 5: Inclined Plane with Friction<\/h3>\n\n\n\n

A block is placed on an inclined plane of angle 30\u00b0. The coefficient of friction is 0.2. Determine whether the block will slide.<\/p>\n\n\n\n

This is one of the most conceptual problems in the Top 5 Laws of Motion Questions<\/strong>. The comparison is between downward force and friction.<\/p>\n\n\n\n

Downward component = mg sin\u03b8 = 0.5 mg. Friction = \u03bcmg cos\u03b8 = 0.2 \u00d7 0.866 mg = 0.1732 mg. Since 0.5 mg is greater than friction, the block will slide.<\/p>\n\n\n\n
