Ulearno JEE Main 2026 Physics – Kinematics Smart Revision eBook

Kinematics

Kinematics is one of the foundational chapters in JEE Main Physics. It deals with the motion of objects without considering the forces causing the motion. This chapter covers motion in one dimension, motion in two dimensions, projectile motion, and relative motion, forming the base for advanced mechanics topics.

Topics Covered

• Distance and Displacement
• Speed and Velocity
• Acceleration
• Equations of Motion
• Graphical Analysis of Motion
• Motion in One Dimension
• Motion in Two Dimensions
• Projectile Motion
• Relative Motion
• Uniform Circular Motion

Important Formulas

First Equation of Motion:
v = u + at

Second Equation of Motion:
s = ut + ½at²

Third Equation of Motion:
v² = u² + 2as

Projectile Time of Flight:
T = 2u sinθ / g

Maximum Height:
H = u² sin²θ / 2g

Horizontal Range:
R = u² sin2θ / g

JEE Main Preparation Tips

• Master equations of motion and graph interpretation.
• Practice projectile motion numericals regularly.
• Focus on relative motion concepts.
• Strengthen vector resolution for 2D motion.
• Solve previous year JEE Main questions for speed and accuracy.
