NCERT lines NEET asked again and again

Read these lines from your NCERT book twice: NEET has built questions on each of them more than once.

Write K = p²/2m. For equal momentum the lighter body has more KE ; for equal KE, p∝√m . Many NEET ratio questions end here.

Energy stored in a stretched spring is (1/2)kx², so stretch 4 times means energy 16 times . Compression or extension, it is always positive.

AIPMT 2003AIPMT 2006NEET 2023

A string-tied body needs vₜₒₚ ≥ √gL , so the bottom speed must be at least √5gL . On a loop track this means starting height (5/2)R.

AIPMT 2003NEET 2016NEET 2018

Set dU/dr = 0 to get the equilibrium position. It is stable when d²U/dr²>0 , which means U is at a minimum there.

AIPMT 1995AIPMT 2012

If the engine delivers constant power from rest, Pt = (1/2)mv² gives v∝√t . Rate of KE given to a water jet is (1/2)ρAv³.

AIPMT 2009AIPMT 2012

In a head-on elastic collision with a target at rest, maximum energy transfer happens when masses are equal . Equal masses simply exchange velocities.
