What does “Instantaneous velocity” actually mean in Kinematics, and why does it matter for NEET?
the velocity at a single instant — the slope of the position–time graph at that point.

I keep getting “Instantaneous velocity” questions wrong in Kinematics. What's the trap?
confusing average velocity (total displacement/total time) with instantaneous velocity.

What does “Acceleration” actually mean in Kinematics, and why does it matter for NEET?
the rate of change of velocity; it is a vector, so direction matters.

I keep getting “Acceleration” questions wrong in Kinematics. What's the trap?
assuming acceleration is zero whenever velocity is zero (e.g. at the top of a throw, v=0 but a=−g).

What does “Equations of motion” actually mean in Kinematics, and why does it matter for NEET?
the v=u+at family that connects u, v, a, s and t — valid only for constant acceleration.

I keep getting “Equations of motion” questions wrong in Kinematics. What's the trap?
using them when acceleration is changing.
