Newton's Laws of Motion are fundamental to understanding the motion of objects. Here are the key formulas and concepts for JEE Mains:

Newton's First Law of Motion (Law of Inertia):

  • An object at rest will remain at rest, and an object in motion will continue to move in a straight line with constant speed, unless acted upon by an unbalanced force.

Newton's Second Law of Motion:

  • The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.

  • Formula: F = ma
    • F: Net force (N)
    • m: Mass of the object (kg)
    • a: Acceleration of the object (m/s²)


    Newton's Third Law of Motion (Law of Action and Reaction):

    • For every action, there is an equal and opposite reaction.


    Important Formulas and Concepts:

    • Weight: W = mg
      • W: Weight of the object (N)
      • m: Mass of the object (kg)
      • g: Acceleration due to gravity (9.8 m/s²)
    • Friction: The force that opposes the relative motion between two surfaces in contact.
      • Static friction: Fs ≤ μsN
      • Kinetic friction: Fk = μkN
        • μs: Coefficient of static friction
        • μk: Coefficient of kinetic friction
        • N: Normal force
    • Tension: The force transmitted through a string, rope, or cable when it is pulled taut.
    • Normal force: The force exerted by a surface on an object in contact with it, perpendicular to the surface.
    • Centripetal force: The force that causes an object to move in a circular path.
      • Fc = mv²/r
        • Fc: Centripetal force (N)
        • m: Mass of the object (kg)
        • v: Velocity of the object (m/s)
        • r: Radius of the circular path (m)


    These formulas and concepts are essential for understanding Newton's Laws of Motion and solving problems related to mechanics in JEE Mains. Practice solving a variety of problems to solidify your understanding and improve your problem-solving skills.
