Newton's laws of motion imp formulas for jee mains

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.
