What does “Equations of motion” actually mean in Kinematics, and why does it matter for JEE?
the v=u+at family that connects u, v, a, s and t — valid only for constant acceleration.
In simple words: the v=u+at family that connects u, v, a, s and t — valid only for constant acceleration. Getting Equations of motion clear matters because JEE questions on Kinematics usually test this idea directly, not just a formula you memorised.
Key point
Equations of motion
Common mistake
using them when acceleration is changing.
Memory tip
if a is not constant, you must use calculus, not these three equations.
