Core Concepts

  • Distance vs Displacement

    Distance is scalar (path length), Displacement is vector (change in position).

  • Speed vs Velocity

    Speed is scalar (distance/time), Velocity is vector (displacement/time).

  • Acceleration

    Rate of change of velocity. Uniform acceleration implies constant change in velocity.

Common Mistakes (JEE/NEET)

  • Sign Convention

    Always define positive direction. If 'up' is positive, acceleration due to gravity (g) is negative (-9.8 m/s²).

  • Stopping Distance

    When a vehicle stops, final velocity v = 0. Do not assume time is given.

  • Vector Direction

    Velocity and acceleration can have opposite signs — object slows down but still moves forward.

Essential Formula Sheet

Fundamental equations of motion

Velocity & Acceleration
v = u + at
Final velocity equals initial velocity plus acceleration times time.
v = final velocity u = initial velocity
Displacement (Time known)
s = ut + ½at²
Distance covered under constant acceleration with time known.
s = displacement t = time
Displacement (Time unknown)
v² = u² + 2as
Useful when time is not given or required in the problem.
No time needed Energy relation
Average Velocity
s = ½(u + v)t
Displacement equals average velocity multiplied by time interval.
Average velocity (u+v)/2
